Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar
with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or
failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified. In customer applications
requiring a very high level of operational safety and especially in customer applications in
which the malfunction or failure of an electronic component could endanger human life or
health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by
means of suitable design of the customer application or other action taken by the customer
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order. We also
reserve the right to discontinue production and delivery of products. Consequently, we
cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version
of the "General Terms of Delivery for Products and Services in the Electrical Industry"
published by the German Electrical and Electronics Industry Association (ZVEI).
7. The trade names EPCOS, BAOKE, Alu-X, CeraDiode, CeraLink, CSMP, CSSP, CTVS,

SIFERRIT materials
Based on IEC 60401-3, the data specified here are typical data for the material in question, which
have been determined principally on the basis of toroids (ring cores).
The purpose of such characteristic material data is to provide the user with improved means for
comparing different materials.
There is no direct relationship between characteristic material data and the data measured using
other core shapes and/or core sizes made of the same material. In the absence of further agreements with the manufacturer, only those specifications given for the core shape and/or core size in
question are binding.

PQ cores
General information
PQ cores
PQ cores for switch-mode power supplies
These cores are a preferred shape for power conversion. The main advantages compared to
conventional round or rectangular E type cores are the optimized round leg and wider outer surface.
The round leg reduces winding length and hence copper cost in production and the wider surface
area lowers the thermal resistance by offering a larger area for heat dissipation. The shape also
provides better shielding to the winding.
EPCOS offers the extended PQ series from PQ16 up to PQ40 and PQ50 in the typical power
materials (N87, N97, N95, N49 and N92). PQ cores are supplied in sets. Selected bobbins are also
available.

A L value is measured acc. to IEC62044-2. An appropriate wringing of cores with polished surface is used to
improve reproducibility of the measurement. (It is recommended to rub the mating surfaces themselves six times
in a circular or elliptic arc that matches the core profile before measuring A L value).

A L value is measured acc. to IEC62044-2. An appropriate wringing of cores with polished surface is used to
improve reproducibility of the measurement. (It is recommended to rub the mating surfaces themselves six times
in a circular or elliptic arc that matches the core profile before measuring A L value).

PM cores
General information
PM cores
PM cores are particularly suitable for use in transformers handling high powers in the frequency
range up to 300 kHz. For numerous design tasks in telecommunications and industrial electronics
(e.g. power pulse transformers in radar transmitters, antenna matching networks, machine control
systems, thyristor firing transformers, energy storage chokes in switch-mode power supply equipment and others), the pot core shape offers various advantages: wide flux area for high power at a
minimum number of turns, thus causing only low magnetic leakage and stray capacitance, as well
as good shielding owing to the closed form, precisely ground air gaps, straightforward assembly and
economic mounting.
A family of large pot cores, briefly designated PM cores (for Pot core Module), is presented in the
following.
Due to the weight of these pot cores, particularly in the case of the large cores 87/70 and 114/93,
mounting on PC boards may not always be possible. In these cases, the coil former should be
mounted with its terminals upwards.

EP, EPX, EPO cores
General information
EP, EPX, EPO cores
EP, EPX and EPO cores are typically used for transformer applications. Their cubic shape provides
an excellent volume ratio to total space used and permits high PCB packing densities. The compact
design and the broadband materials used (N30, T38, T57, T65 and T66) ensure low magnetic
leakage, low signal distortion and excellent properties for broadband small-signal transmission
(xDSL).
EP cores are increasingly being used for power applications. Here we recommend the series EP 7
through EP 20 made of N87 for operation up to about 300 kHz.
Matching pinned and SMD coil formers suitable for automatic processing and shielding accessories
(yoke, clamp or cap yoke) complete the product line.

EP, EPX, EPO cores
General information
Tolerances for EP cores
Increasing use is now being made of gapped EP cores with AL values and ultra-low AL tolerances,
especially for broadband transformers.
The tolerances for EP cores have consequently been defined with consideration of optimized process parameters for all materials with an initial permeability P i in the region of 1400 to 15000 as a
step function (see figure below).
The “quantized” AL step values should preferably used. They are still available in their respective
lower tolerance ranges. Thus a tolerance of r5% can be determined for an EP 13 made of T38
material for an AL value of 250 nH.
With this type of tolerance definition, EPCOS has defined standard AL values and the associated
tolerances for the first time.

P cores (pot cores)
General information
P cores
1
General information
P cores (Pot cores) are available in a wide range of sizes; 7 types in our product line comply with
IEC 60133. We offer a choice of different SIFERRIT materials, which permits the cores to be used
for a large variety of applications to over 100 MHz. Since the wound coil is completely enclosed by
the ferrite core, P cores feature low magnetic leakage. They can be easily and precisely adjusted
to the most manifold inductor requirements.
We naturally also supply the appropriate accessories for each core version. Most of the cores are
available with threaded sleeves and screws for precision inductance adjustment. Adjustment curves
are given for this purpose. These relate to the particular recommended combination of screw
core/core material AL value and must be understood as typical values.
2
Applications
The cores are suitable for:
■ High-quality resonant circuit inductors (filters) with high inductance stability (materials K1, M33,
N48).
■ Low-distortion broadband small-signal transformers in materials T38 and N30 with high A L value
■ Power applications. Here, pot cores without center hole made of material N87 are used as
standard. As a result of their larger effective magnetic cross-sectional area, these types are
characterized by a higher A L value, better flux density distribution and, consequently, a reduced
power loss.
3
Marking
The material and the AL value are always stamped on P cores with a diameter > 5.8 mm, the
material and “o. L.”(= without air gap) are stamped on ungapped cores. Only one core half of the
two comprising a set carries the marking. With cores having an unsymmetrical air gap (the total air
gap is ground into one half) the ground half carries the marking, with cores including a glued-in
threaded sleeve the half without sleeve is marked.
4
Power loss
For each core type with power materials the maximum power loss is specified in W/set. The flux
density has been calculated on the basis of a sinusoidal voltage and is referred to the minimum
cross-sectional area Amin.

P core halves for proximity switches (PS cores)
General information
P core halves for proximity switches (incl. PS cores)
Inductive proximity switches can be used as noncontacting motion detectors and output indicators.
Possible applications:
– Detection of the final position on conveyor belts
– Counters at rotating parts
– Contactless detection of pointer position of pointer-type measuring and control instruments
The advantages of proximity switches are bounceless switching, no mechanical wear, insensitivity
to contamination and detection of metallic parts only.
We supply P core halves/PS cores with diameters ranging from 7.35 to 150 mm for inductive
proximity switches. Their dimensions are matched to standardized switches. Maximum operating
distances can thus be achieved for the individual P core sizes. The SIFERRIT material N22 is
particularly suitable for the frequency range from 0.1 to 0.8 MHz. The material M33 is additionally
available for higher frequencies (core types with 5.6 to 14.0 mm diameter).
Thermoplastic coil formers can be supplied for most of the core types. This material permits an
operating temperature range of –60 to +120 °C. Consequently, temperatures of up to +120 °C are
also permissible during encapsulation.

E cores
General information
E cores

Core shapes and materials
The preferred materials for manufacture of E cores are the SIFERRIT materials N27, N87, T46 and
N30. N27 is recommended for power applications in the frequency range up to about 100 kHz and
N87 for the frequency range up to 500 kHz; EFD cores made of N49 are particularly suitable for
frequencies f >500 kHz. These materials feature a high saturation flux density and low power loss.
Material N30 is particularly suitable for broadband small-signal applications and also for interference suppression chokes.
The E core spectrum contained in this data book comprises five basic core shapes, which can be
used not only for transformers but also for chokes with a power capacity of up to 10 kW.
a) Types with round center leg
We offer the following types:
■ ER cores
■ EQ cores
■ ETD cores to IEC 61185 (Economic Transformer Design)
E cores with round center leg offer the advantage of easy winding, particularly when thick winding
wires are used, compact mounting dimensions and wide openings on each side. ETD cores have
the additional benefit of an almost constant cross section along the magnetic path. A wide variety
of optimized accessories is available. ER cores in sizes 9.5 and 11/5 are particularly suitable for
designing transformers with low overall height and high inductance. They come in material T38 for
broadband applications plus in N87 and N49 for power transformers for frequencies up to and over
500 kHz.
b) Types with rectangular center leg
■ E cores
■ EFD cores (Economic Flat Transformer Design); EV cores
The conventional E cores with rectangular center leg are available in a wide variety of sizes.
EFD cores have an optimized cross section and enable the design of very flat and compacts transformers, even for high-frequency applications.
c) ELP cores (E Low Profile)
ELP cores enable the design of very flat transformers and feature excellent thermal performance
due to the large core surface. ELP cores are now specified in IEC 62317-9.
Please read Important notes on page 2
and Cautions and warnings on page 609.

Ordering, marking, delivery
E cores are supplied as single units (except ER 9.5, ER 11 and ER 14.5/6: in sets), with each packing
unit (PU) exclusively containing cores with or without shortened center leg (air gap dimension „g“).
Gapped EFD cores are supplied with toleranced AL value as specified in the data sheets. All other
E cores are availble with toleranced AL value on request.
There are two possibilites of air gap distribution, either symmetrical (each core of a set has the same
air gap size) or unsymmetrical (a gapped core is combined with an ungapped core).
E and U cores are marked using the same system. Hence, the following description applies to both
core shapes.
■ E 5, E 6.3, E 8.8, EFD 10 and I cores are not marked.
■ E cores are marked by an ink-jet printer on the outside of the legs (figure 1).

E cores
General information
Depending on their height and width, there is not enough space on all cores for complete marking,
meaning that simplification is necessary. So only the material and the date code will be stated. This
ensures that there is space for at least one complete marking (two characters per line) on the core.
To avoid confusion of names like N27 and N72, the beginning of the material designation coincides
with the position of the letter in the date code.
Example:
727272
2B2B2B
means N27 (not N72)
Remark: in some exception cases parts are stamped with rolls on the back (gapped EFD 15 for
example).
Date code:
Date coding is based on a two-week period (see tables, counting by calendar weeks CW).
In the following year lines 1 and 2 will we swapped (material and date code). The position of letters
and digits will not be swapped. Counting started in 1996.

As is the case with ungapped cores, a certain degree of roughness cannot be avoided on the
ground surfaces of the outer legs.
4
Cores with toleranced A L value
The tolerance of the AL value depends on the magnitude of the A L value and the core shape.
Tolerance figures are therefore given only on a core-type-specific basis.
5
Calculation formulae
Calculation formulae a) and b) apply to the AL value under the following measuring conditions:
Measuring flux density B d 0.25 mT, measuring frequency f = 10 kHz,
measuring temperature T = 25 r3 °C, measuring coil: N = 100 turns, fully wound
a) Air gap and AL value
The typical AL value tabulated in the individual data sheets refers to a core set comprising a gapped
core with dimension „g“ and an ungapped core with „g“ approx. 0.
By inserting the core-specific constants K1 and K2, a nominal AL value can be calculated for the
materials N27 and N87 within the relevant quoted air-gap validity range:
1
----------
A L K2
s = §© -------·¹
K1
s = > mm @
A L = > nH @
Production variations with regard to Pi and grinding quality should be taken into account additionally.
b) DC magnetic bias I DC
By using the core-shape-related factors K3 and K4, nominal values can be determined for the DC
magnetic biasing characteristic of E, ETD and EFD cores made of N27 and N87 and ELP cores
made of N87 at temperature 25 °C and 100 °C.
The direct current IDC at which the A L value drops by 10% compared to the AL value without
magnetic biasing (IDC = 0 A) is determined for a coil with 100 turns.
Calculation of IDC at T = 25 °C:
The factors K3 and K4 for T = 25 °C and the AL value without magnetic biasing are inserted into the
equation for the calculation.
Please read Important notes on page 2
and Cautions and warnings on page 609.

Magnetic characteristics
The set characteristics 6 l/A, le, Ae, Amin and Ve required for the calculation of field strength, flux
density and hysteresis losses have been determined to IEC 60205 (Amin = minimum cross section
relative to the nominal dimensions).
7
Core losses
The maximum power loss for each core type is specified in W/set together with the measurement
parameters. The flux density has been calculated on the basis of a sinusoidal voltage and is referred
to the minimum cross-sectional area Amin.
8
Accessories
The coil formers for all ETD, EFD and ER cores and most of the E cores are designed so that they
can be wound fully automatically.
With the ETD cores and most E cores, each core half and its mounting assembly can be fitted to
the coil former from the same side, thus permitting simple fully automatic assembly.
If coil formers are used for cores with a rectangular cross section (E cores), the indication of the
winding height represents only a theoretical value. The use of thicker wires or litz wires results in a
gradual rounding of the winding from layer to layer. In such cases the planned winding design
should be verified by means of a winding test.
SMD coil formers are available as accessory.

EQ cores
General information
EQ cores
EQ planar cores for power applications
Integrating ferrite cores into the PCB has become a common technology in the power supply market. In those low-profile designs ferrite planar cores with low losses and high saturation are widespread. The trends are increasing the power density of the throughput transformer and the current
in the output inductor. Ferrite cores are considered a key component for these targets. EPCOS has
extended the range of planar ferrite cores to meet the new requirements.
Besides the standard ELP core series EPCOS offers now extended series of planar cores with
round center post: EQ 13 to EQ 30 and ER 9.5 to ER 32. This wide range of shapes improves the
design capabilities for individual power converter solutions. Customer-specific heights can be supplied as well as different air gap requirements for all series.
All EPCOS planar cores are available in the well-known EPCOS power materials. Preferred materials are N97 and N92. N97 is optimized for low losses, N92 for high saturation current in the output
chokes. N87 is suitable for standard requirements. For frequencies higher than 400 kHz, we recommend N49.

ER cores
General information
ER cores
Example of an assembly set ER 42
ER cores are the ideal answer when compact winding structures with low leakage inductance are
needed. The round center leg is an advantage together with thick wires or bands.
Because of their good thermal response, ER cores are especially suitable for applications with high
power density. E.g. they are used in flyback converters for TVs and monitors.

U and UI cores
General information
U and UI cores
1
Core shapes and materials
U cores of rectangular cross section and I cores are made of SIFERRIT materials N27 and N87.
Owing to their high saturation flux density, high Curie temperature and low dissipation losses, they
are suitable for power, pulse and high-voltage transformers. UU and UI cores are preferred for power ratings, since they can be combined in various ways (see illustration above) to produce transformers in the kilowatt range.
2
Ordering, marking and delivery
U and I cores are supplied as single units, not as sets.
U cores with one shortened leg ( air gap) are available on request.
U and I cores are not marked.
3
AL and core loss specification
The corresponding test results are tabulated separately for each core shape.
a) A L value (see also “General – Definitions”, page 127)
The AL value is measured with a fully wound 100-turn coil at a flux density of B = 0.25 mT and a
frequency of f = 10 kHz. The temperature of the core is equal to room temperature.
b) Power loss P V
The dissipation loss is specified in W/set. The data are maximum values under the specified
measuring conditions. The flux density has been calculated on the basis of a sinusoidal voltage
and is referred to the minimum cross-sectional area Amin of the core.

Toroids (ring cores)
General information
Toroids (ring cores)
Our product line includes a wide range of toroids with finely graded diameters ranging from 2.5 to
202 mm.
Other core heights can be supplied on request. All cores are available in the usual materials.
Applications
■ Toroids are primarily used as EMC chokes for suppressing RF interference in the MHZ region
and in signal transformers.
Typical applications for toroids of NiZn ferrites are LAN chokes. One of the materials available
for this purpose is K10; other materials on request.
The following high-permeability MnZn materials are available for interference suppression:
– R 2.5 through R 12.5 for telecommunications, e.g. ISDN (N30, T38, T46)
– R 13.3 through R 26 for power line chokes (N30, T65, T35, T37, T38)
– >R 34 for chokes and filters in industrial use (T65)
■ Toroids are also increasingly used for power applications. Here, the typical values for amplitude
permeability and power loss, as summarized in the section on “SIFERRIT Materials ” (page 33),
are applicable to the special power materials.
Coating
Toroids are available in different coating versions, thus offering the appropriate solution for every
application. The coating not only offers protection for the edges but also provides an insulation function.
For small ring cores, we have introduced a parylene coating which features a low coating thickness
and high dielectric strength.

Toroids (ring cores)
General information
Dielectric strength test
The following test setup is used to test the dielectric strength of the insulating coating: A copper ring
is pressed to the top edge of the ring. It touches the ferrite ring at the edges (see diagram).
The test duration is 2 seconds.
Ferrite ring
Vrms
Metal poles
Chamfer
Large toroidal cores use thick wires that are partially subjected to high mechanical stress during
winding. This can damage the wire insulation as well as the coating of the cores, thus reducing the
breakdown voltage. To avoid this, EPCOS toroids have a chamfer. This prevents any insulation
damage, and produces uniform coating thickness at the same time.
