Installation space requirements
1) A minimum distance of 20 mm between the capacitors is necessary to maintain sufficient cooling.
2) Keep at least 20 mm space above the capacitor and do not attach any mounting components at the
crimp or on top. This gap will allow a longitudinal extension of the can in order to ensure that the overpressure disconnector can fully extend.

Display of ordering codes for TDK Electronics products
The ordering code for one and the same product can be represented differently in data sheets, data books,
other publications, on the company website, or in order-related documents such as shipping notes, order
confirmations and product labels. The varying representations of the ordering codes are due to different
processes employed and do not affect the specifications of the respective products. Detailed
information can be found on the Internet under www.tdk-electronics.tdk.com/orderingcodes.

Film Capacitors - Power Electronic Capacitors
General purpose applications
B3237X Series
FilterCap MKD-AC – Single phase
Terms
Design
The winding element of the MKD capacitor consists of metallized polypropylene film. This winding
construction achieves low losses and a high pulse-current withstand capability. Soft PU resin is used
for impregnation of the capacitor.
Contacting
The end faces of the windings are contacted by metal spraying to ensure a reliable and low-inductance
connection between the leads and layers. The leads are welded or soldered to these end faces, brought
out through insulating elements (plastic) and soldered to the terminals.
Impregnation
All hollows between the windings and between the windings and the case are filled with an impregnating
agent. Besides increasing dielectric strength, this improves heat dissipation from inside a capacitor.
The impregnating agents that we use are free of PCB and halogens.
Self-healing
All MKD capacitors are self-healing, i.e. voltage breakdowns heal in a matter of microseconds and
hence do not produce a short circuit.
Breakdowns can occur under heavy electrical load as a result of weaknesses or pores in the dielectric.
The integrity of self-healing capacitors is not affected by such breakdowns.

Film Capacitors - Power Electronic Capacitors
General purpose applications
B3237X Series
FilterCap MKD-AC – Single phase
When a breakdown occurs, the dielectric in a breakdown channel is broken down into its atomic
components by the electric arc that forms between the electrodes. At the high temperatures of as much
as 6000 K, a plasma is created that explodes out of the channel region and pushes the dielectric layers
apart. The actual self-healing process starts with the continuation of the electric arc in the propagating
plasma. Here the metal layers are removed from the metal edges by evaporation. Insulation areas are
formed. The rapid expansion of the plasma beyond the areas of insulation and its cooling in the areas
of less field strength allow the discharge to extinguish after a few microseconds.
The area of insulation that is created is highly resistive and voltage-proof for all operating requirements
of the capacitor. The self-healing breakdown is limited in current and so it does not represent a short
circuit. The self-healing process is so brief and low in energy that the capacitor also remains fully
functional during the breakdown.

C, RS and LS are magnitudes that vary in the frequency domain (AC).
RP is a magnitude defined in DC (insulation resistance).
Rated capacitance CR
It is referred to a test temperature of +20 ℃ and a measuring frequency range of 50 Hz to 1 kHz.
Capacitance tolerance range
It is the range within which the actual capacitance may differ from rated capacitance. The actual
capacitance is to be measured at a temperature of +20 ℃. This range results from variances in materials
and manufacturing processes. The standard manufacturing tolerance for PP film capacitors is ±10% or
‘K’ tolerance or ±5%, ‘J’ tolerance.

Capacitance drift
Capacitance is subject to irreversible in addition to reversible changes, i.e. capacitance drift, the sum
of all time-dependent, irreversible changes of capacitance during operating life. This variation is stated
in percent of the value at delivery. The typical figure is +1/−3%.
Rated AC voltage VR
The maximum operating peak recurrent voltage of either polarity of a reversing type waveform for which
the capacitor has been designed.
Unlike what is common in other standard (e.g. B32304* 3–phase capacitor series for PFC application)
therefore, the rated voltage VR is not the RMS value, but the maximum or peak value of the capacitor
voltage. The voltage at which the capacitor may be operated is dependent on other factors (especially
current and frequency) besides rated voltage.
Voltage VRMS
It is the Root Mean Square (RMS) voltage of maximum permissible value of sinusoidal AC voltage in
continuous operation.

Self-inductance L
The self-inductance is produced by the inductance of the terminals and the windings. Because of the
special kind of contacting in self-healing capacitors (large area metal spraying covering all windings),
the self-inductance is particularly low. It allows the resonance frequency to be determined:

∙C
The resonance frequency is high for all capacitors accordingly.
Insulation Resistance (Rins)
The dielectric of a capacitor has a large area and a short length. Even if the material is a good isolator
there always flows a certain current between the charged electrodes (the current increases
exponentially with the temperature). This leakage can be described as a parallel resistance with a high
value, an Insulation Resistance.

Dielectric dissipation factor tan δ0
The dissipation factor tan δ0 of the dielectric is assumed to be constant for all capacitors in their
frequency range of use. The figures stated in data sheets apply to rated operation.
Expected Fit rate λ
The FIT (Failure In Time) of a component is defined as the number of expected failures in 109 hours of
operation.
The FIT rate is calculated on the basis of the number of components operating in the field and the
estimated hours of operation. All the reports of failures are taken into consideration for this calculation,
which is updated every year. The other values in the graph are given as indication and calculated based
on acceleration factors.
The failure criterion is capacitance drop higher than 3%.

Thermal design
In order to scale a capacitor correctly for a particular application, the permissible ambient temperature
has to be determined. This can be taken from the diagram “Permissible ambient temperature TA vs
total power dissipation P”after calculating the power dissipation (for further details please check

The temperature difference depends on a large number of different factors. The thermal resistance is
a function of several parameters such as the working temperature and the power dissipation of the
capacitor.
After installation of the capacitor, it is necessary to verify that maximum hot-spot temperature is not
exceeded at extreme service conditions. For detail calculations, please refer to single datasheet part
number for further details.
Life expectancy tLD
The life expectancy tLD is based on the exclusive effect of Voltage and Temperature (hot-spot Ths)
applied to the capacitor dielectric and electrodes (other factors are not considered in the model such
as environmental or mechanical effects).
Hot Spot Temperature (Ths): as the sum of ambient temperature plus the heating induced by the current
(IRMS) in the dielectric which is measured inside of capacitor. Current is an indirect parameter under
consideration which affects the temperature Ths.

Cautions and warnings
Capacitors with dents of more than 1 mm depth or any other mechanical damage must not be used.
Check the tightness of the connections / terminals periodically.
The energy stored in capacitors may be lethal. To prevent any risk of shock, the capacitors must be
discharged and short-circuited before handling.
Failure to follow cautions may result in the worst case in premature failure, bursting and fire.
Safety
Electrical or mechanical misapplication of capacitors may be hazardous. Personal injury or property damage
may result from bursting of the capacitor or expulsion of molten material due to mechanical disruption of the
capacitor.
Ensure good, effective grounding for capacitor enclosures.
Observe appropriate safety precautions during operation (self-recharging phenomena and the high energy
stored in capacitors).
Handle capacitors carefully, as they may still be charged even after disconnection.
The terminals of capacitors, connected busbars and cables as well as other devices may also be energized.
Follow good engineering practice.
The maximum permissible fault current (AFC) of 10 kA in accordance with the UL 810 standard must be
assured by the application.
Thermal load
After installing the capacitor, verify that the maximum hot-spot temperature is not exceeded under extreme
operating conditions.
Mechanical protection
The capacitor has to be installed to assure that no mechanical damage or dents in the case occur.
Storage and operating conditions
Do not use or store capacitors in corrosive atmospheres, especially where chloride gas, sulfide gas, acid,
alkali, salt or the like are present. In dusty environments, regular maintenance and cleaning, especially of the
terminals, is required to avoid creating a conductive path between phases and/or phases and ground.
Overpressure disconnector
To ensure full functionality of an overpressure safety disconnector, the following points must be observed:
1. The elastic elements must not be hindered, i.e.
Connecting lines must be flexible leads (cables)
There must be sufficient space (min.15 mm) for expansion above the connections
The metal cover must not be retained by rigid parts such as busbars.
2. The stress parameters of the capacitor must be within the IEC 61071 specification.
Service life expectancy
Electrical components do not have an unlimited service life expectancy: this also applies to self-healing
capacitors. The maximum service life expectancy may vary depending on the application in which the
capacitor is used.

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 we are 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 a 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.tdk-electronics.tdk.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 our General Terms and
Conditions of Supply.
7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard.
The IATF certifications confirm our compliance with requirements regarding the quality
management system in the automotive industry. Referring to customer requirements and customer
specific requirements (“CSR”) TDK always has and will continue to have the policy of respecting
individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateral
requirements, we hereby like to emphasize that only requirements mutually agreed upon can
and will be implemented in our Quality Management System. For clarification purposes we like
to point out that obligations from IATF 16949 shall only become legally binding if individually agreed
upon.
