Plastic Film Capacitors
Guidelines and precautions (Common)
1. Operating voltage
For the film capacitor varies the maximum applicable voltage depending on the applied voltage waveform, current waveform,
frequency, ambient temperature (capacitor surface temperature), capacitance value, etc. Use within the specified values
by checking the voltage waveform, current waveform, and frequency applied to both ends of the capacitor prior to use.
(In the case of high frequency, the permissible voltage varies with the type of the capacitor. For details please see the
relevant specifications.)
1.1 Rated voltage (Note 1)
・ The rated voltage refers to the maximum voltagethat can be applied continuously within the category temperature range.
If used beyond the rating, it may induce insulation breakdown of the film and cause short circuit. The product lifetime
abut the maximum rated condition depends on the kind of the capacitor.
・ In a metalized capacitor, which has a self-healing action, short circuit or other failure may not occur immediately after
application of a voltage over the rated voltage, but the insulation resistance is lowered, and it may lead to smoke or fire
depending on the circuit conditions.
・ A noise suppression capacitor ( AC rated voltage) should not be used at high frequency circuit.
Smoke and ignition may be caused by conditions for use.
・ The rated voltage of the capacitor for electronic appliance is usually indicated in the DC voltage except for special
purposes.
1.2 Derating of rated voltage where operating temperature is high
In film capacitors, the usable upper limit temperature (the capacitor surface temperature) is determined by the kind of
dielectric materials.
When used beyond the rated upper limit temperature (usable upper limit temperature), it is necessary to voltage derate
the in certain types (models), while other types (models) cannot be used beyond the rated upper limit temperature.
Be sure to confirm the type of capacitors before using, and when using beyond the rated upper limit temperature, be
sure to reduce the voltage and make sure the capacitor surface temperature is within the usable upper limit temperature
as below. When using at high frequency, however, since the capacitor itself has its own temperature rise, and hence
the following derating ratio cannot be applied.

1.3 Permissible voltage (R.M.S) in current corresponding to DC Rated voltage
・ A noise suppression capacitor ( AC rated voltage) should be used at the primay side power supplies.The design which
premised on use by 50Hz or 60Hz sine wave.
・ In case of applying voltage in alternating current (50Hz or 60Hz sine wave) to a capacitor, permissible voltage(R.M.S).
The capacitor of DC rating should not be used at the primary side power supplies.
1.4 Derating of rated voltage when using at high frequency
When using at high frequency, there is a risk of thermal runaway (smoke, fire) due to self heat generation in the capacitor.
Derate the operating voltage according to the example below.
For use at high frequency, we recommend ECHU(X)/(C), ECWF(A)/(L), and ECWH(A)/(C)/(V) types.

: 40 kHz (sine wave)
: 40 kHz 2.0 Arms

2×3.14×40×103×0.15×10-6
= 53 Vrms
Therefore, the operating voltage at sine wave 40 kHz is lower than to 53 Vrms (derating ratio 58%), as
compared with AC permitted voltage of 125 Vrms at commercial frequency.
(It is necessary to derate until the self heating temperature rise of the capacitor is below the specified value.)
〈Caution〉
(1) Use the peak value (Vo-p) of the Pulse voltage applied between the both terminals of the capacitor within the
DC rated voltage.
(2) When using at high frequency, it may lead to breakdown due to withstand voltage deterioration by self heat
generation. Therefore, measure the self heating temperature rise value of the capacitor, and make sure it is within
the specified.
(3) Protection for safety should be required in the case of the voltage over the rated voltage (permitted voltage) may
be applied to the capacitor due to abnormal action such as trouble elsewhere in the circuit.
2. Permitted current
Film capacitors are low in internal impedance, and hence a very large current may flow depending on the circuit. In particular,
when turning power switch on and off, make sure a very high pulse current may flow.
When a current exceeding the permissible range flows into capacitor, this can cause the capacitance value to deteriorate or
an open circuit condition, temperature rise occurs due to self heat generation, this cause can deterioration of withstand
voltage and result in short circuit, possibly leading to smoke or fire.
In the application, make sure current is within permissible current or self heating temperature is within permissible self
heating temperature rise limit shown on each delivery specifications.
2.1 Permissible current
The permissible current must be considered by dividing into pulse current (peak current) and continuous current
(rms current) depending on the breakdown mode, and when using, therefore, make sure the both currents are within the
permissible values.
2022/1/14
Plastic Film Capacitors
2.2 Permissible current to operating frequency
The film capacitor varies in the frequency characteristic of the dissipation factor (tanδ) depending on the dissipation factor,
and hence the permissible rms current for operating frequency differs depending on the capacitor type. In particular, when
operating at high frequency, the dissipation factor (tanδ) increases, and when using over the permissible current, it may
include the thermal runaway, possibly leading to smoke or fire. Shown below are typical examples of permissible current
by frequency (rms value) of the ECQE(F) type using polyester film and ECWF(A) type using polypropylene film. For detail
inquire us by presenting the operating conditions, or make sure the own temperature rise of the capacitor and the capacitor
surface temperature are within the permissible range in the worst operating conditions.

2.4 Permissible current to pulse current
・ When used in switching circuits or snubber circuits a momentary high current pulse may cause local heat generation.
This causing the capacitance value to deteriorate or an open circuit condition. Local heat generation may also induce
smoke or fire. The pulse permissible current (10000 times) isobtained by the product of dV/dt (V/μs) value that is
entering to the specification and capacitance (μF).
・ The dV/dt (V/μs) value of a film capacitor is determined by the element structure, and in the metalized type, in particular,
the internal evaporated electrode and external takeout electrode are connected by metalized contact (metal spraying),
and hence due caution is needed because the upper limit of dV/dt value is low.
・ The dV/dt values corresponding to rated voltage and capacitance value of representative types are shown in page 6.
When used in a high current pulse circuit, check the pulse permissible current (Ao-p).
Please contact with us, If pulses are applied more than 10,000 times.
<How to determine pulse permissible current>
When voltage V(V) is applied to capacitor C (F for farad), the electric charge Q(C) is expressed in formula ①.
Q=C・V ‥‥‥‥ ①
The charging current I(A)flow in the capacitor at this time is expressed in formula ②.
I=dQ/dt ‥‥‥‥ ②
Differentiating both sides of formula ① by timet and putting into formula ② yields formula ③.
dQ/dt = C ・ dV/dt
I = C ・ dV/dt ‥‥‥‥ ③
Therefore, the pulse current is determined as theproduct of the capacitance value C (μF) and voltage change dV/dt
per μs.
(Example)
In the case of ECQE4224KF (permissible dV/dt)
Rated voltage
: 400 V.DC
Capacitance
: 0.22 µF
Permissible dV/dt value : 37
Pulse permissible current : 0.22(μF)×37 ≒ 8Ao-p
(however, number of repetitions is 10,000 times or less), that is, momentary pulse current can be used up to 8 Ao-p.
Make sure the rms current is within the permissible value.

Caution :
Protective means for safety should be provided in case the pulse and rms current may exceed the permissible values due
to abnormal action such trouble elsewhere in the circuit.
*: Asterisk denotes the lead pitch.
The value of dV/dt is mainly determined by the lead spacing (element width) and element sectional area.
3. Operating temperature range
3.1 Own temperature rise
When the film capacitor is used in an AC circuit, especially in high frequency application, the capacitorgenerates heat by
itself from the flow of current. If the self heat generation is large, the capacitor may deteriorate, and smoke or fire may be
occur. Check the self heating temperature rise value in actual conditions of use, and use within the limit specified.
Measure the own temperature rise value in indoor, wind-free condition.
※ The details of self heating temperature rise value are described in the specification. (Please contact us details as
the specifies value varies by each type.)
3.2 Operating temperature range
The operating temperature range of the film capacitors varies with the dielectric material (kind of films), and the usable
temperature range is specified in the each model. It must be noted, however, that the temperature range mentioned in the
catalogue is the surface temperature of the film capacitor, not the ambient temperature of the capacitor. In actual use, make
sure the sum of the ambient temperature +capacitor’s self heating temperature rise value (within specified value), that is, the
capacitor surface temperature should be within the rated operating temperature.
〈Caution〉
When used above the specified operating temperature, dissipation factor (tanδ) increase, and the self heat generation may
exceed the permissible value, possibly causing deterioration of dielectric film, short circuit, andsmoke or fire.
If there is cooling plate of other part or any resistance heated to high temperature near the film capacitor, the capacitor may
be locally heated by the radiation heat, exceeding the operating temperature range, and smoke or fire may be caused.
Check the capacitor surface temperature at the heat source side.

4. Other cautions
4.1 Flame retardation
The dielectric film is not a flame retardant material.
In the ECQE , ECWF, and ECWH types, flame retardant epoxy resin (94V-0) is used in the coating resin.
4.2 Environments of use
4.2-1 When used in humid environments
When used for a long period in humidenvironments, the elements absorb moisture through the coating with the
passing of the time. The water oxidizes the electrode (evaporated film and metalized contact), and leads to trouble.
Also, make sure the capacitance value can be very large depending on type of the capacitor.
4.2-2 When using in high temperature environment
When ECQUG is used in high temperature environment (more than 70℃), it may be possible to cause leaking oil
from the capacitor. However, the quality and reliability of the capacitor is not affected by the leaking oil. But, please
don't use the part which may cause a point of tact obstacle by oil and this condenser by a same set.
4.2-3 Cautions on gas atmosphere
When using in the oxidizing gas such as hydrogen chloride, hydrogen sulfide and sulfurous acid, the evaporated
electrode (Aluminum) or metalized contact (zinc compound) may be oxidized, may result in smoke or fire.
Avoid such atmosphere.
4.2-4 When using by resin coating
・ When using resin coating or resin potting components to improve humidity resistance or gas resistance, or to
fix parts in place. Please contact with us.
・ The solvent or the constituent in the resin may permeate into the metalized contact or electrode (aluminum foil or
evaporated film) to deteriorate characteristics.
・ When hardening the resin, chemical reaction heat (curing heat generation) occurs, which may adversely affect
the capacitor.
・ In the case of the lead type capacitors, be sure to test and evaluate enough for the thermal stress to the capacitor.
4.2-5 Other
・ When using in the following conditions, the characteristic may be deterioration. Please don't use at such conditions.
The place that took water or oil.
The place that exposed to the direct sunlight.
The place that radiated ozone, ultraviolet rays and radiation rays.
・ Please consider so that dust doesn't collect. That will be the cause of the characteristic deterioration (short circuit, etc.).
4.3 Changes in capacitance value over time
・ The capacitor characteristics change characteristic depending on its ambient conditions and environmental conditions.
In natural conditions, there is a certain capacitance change due to the humidity of the circumstance. The degree of such
capacitance changes varies with the dielectric material, coating material, and structure.Therefore, we ship considering
these changes, but we only guarantee capacitance value until delivery (without each arrangements.)
・ For use in a circuit where time constant and capacitanceprecision are required, use the products of polypropylene film
ECWFD/(A)/(L) , ECWH(A) or film ECHU(X)/(C) which vary less with time.
4.4 Hum (Buzz)
Hum produced by capacitors due to mechanical vibration of the film is caused by the coulomb force which exists between
electrodes of opposite polarity. A louder hum is produced when applied voltage waveform has distortion, and/or higher
frequency component, etc. Although Hum does not spoil characteristics of capacitors, when being used around the audio
frequency, please check it.
4.5 Storing method, storing conditions
・ It must be noted that the solderbility of the external electrodemay deterioratedwhen stored in an atmosphere filled with
moisture, dust, or a reactive oxidizing gas (hydrogen chloride, hydrogen sulfide, sulfuric acid).
・ Should not location with particularly high temperature and high humidity, and store in conditions not exceeding 35 ℃ and
85 % RH.
・ When it is kept for a long term, the solderbility of the external electrode may deteriorate for oxidation of electrode surface.
So our recommend keeping-period is within 6month. Further, it's different in the condition depending on the items,
so please inquire for details.

Plastic Film Capacitors
4.6 Handling pre cautions
・ Sudden charging or discharging may causedeterioration of capacitor such as shorting and opening due to charging
or discharging current. When charging or discharging, pass through a resistance of 20 to 1000 Ω/V or more.
・ When connecting multiple film capacitors in parallel inwithstandvoltagetestorlifetest,connecta resistance of 20 to
1000 Ω/V or more in series to each capacitor.
・ Be careful not to scratch the capacitor surface with sharp edges (such as screwdriver, soldering iron, pincers,
chassis). Don’t apply excessive load to the lead wire (at the time of re-processing of lead wire, etc.).
・ If the capacitor is dropped by mistake, its characteristics may be damaged. Don’t use such a capacitor.
(If reusing, check the quality sufficiently.)
・ In the case of leaded type capacitor, be careful not to apply excessive force to the lead wire root area, which may cause
cracking or separation in the coating resin near the root area.
・ No dust or water should be permitted to remain on the surface of capacitor terminals as this may cause electrical leakage
or corrosion.
・ When used for noise suppression between lines and between line to earth when voltage is more than 30VAC and more
than 45VDC, covering peripheral resin part by flame retardant material or flame retardant case (for avoiding fire) is
recommended.
・ Chip type capacitor is developed assuming normal use of surface mounting parts.Abnormal use (ex: piling up two
capacitors, mounting capacitor in upright position, etc.) should not be permitted.Please consult us in advance if used in
different way from normal.
4.7 Additional points
・ The precautions in using film capacitors follow the JEITA RCR-2350 D “Safety Application Guide for fixd plastic film
capacitors for use in electronic equipment”. Please refer to the above guideline.
・ Product specifications, materials and other points mentioned in the catalog may be changed without notification.
(Note 1) Rated voltage
The maximum voltage that can be applied continuously in spite of temperature is called as the rated voltage in
our company. It's different from the standards of JIS and IEC.
* Definition of our company
The maximum voltagethat can be applied continuously within the category temperature range.
* Even when needing derating voltage at high temperature, the voltage after derating is called the rated voltage.
Therefore the maximum voltage that can be applied continuously at upper category temperature is being also called
the rated voltage.

(Target product : ECHU, ECWU, ECPU)
1. Soldering
Although there are specific restrictive conditions for the chip type, please check and consider the following items in order
to guarantee soldering quality. Please consult us when using part adhesive for mounting because there is a possibility
that type of adhesive affects the characteristic and the reliability of capacitor.
1.1 Printed wiring board
1.1-1 Selection of printed wiring board
The chip parts are directly mounted on the printed wiring board without using lead wires, and therefore thermal
expansion of the printed wiring board may affect the characteristic of the film chip capacitor, and hence the following
cautions should be observed.

1.1-2 Parts layout on printed wiring board
Film chip capacitors, unlike the leaded type film capacitors do not have coating.
Retaliated heat from a near by heated components may cause the temperature to exceed the usable temperature
range. Without coating, if there is an exposed live part in thevicinity,ashortcircuitmaybeformed through the capacitor.
Consider the arrangement.
1.1-3 Land dimension design
If the land area is wide, tombstone phenomenon (chip rising) is likely to occur in relation to the solder amount.
It is disadvantageous for keeping the mount clearance of the mounting machine, but it is advised to design in the
recommended land dimension shown each specifications.
1.2 Flow soldering
In flow soldering, the chip part capacitor is soaked in molten solder. Film capacitor has lower heat resisting temperature
than other capacitors, therefore cannot be used in flow soldering.
1.3 Reflow soldering
Reflow soldering is a method of soldering by printing a proper amount of cream solder on the mounting land of the
surface mount Printed Wiring Board, putting a film chip capacitor thereon heating, and fusing the cream solder to fix.
1.3-1 Reflow soldering conditions
Perform reflow soldering within the following temperature profile.
(Soldering is within twice, the second dip should be carried after the capacitor itself has returned to
normal temperature.)

1.3-2 Preautions for reflow soldering
・ The film chip capacitor has no coating on the capacitor element, and the internal evaporated electrode may be
deteriorated due to activating agent (halogen, etc.) in the cream solder, and the capacitance value may be decrease,
dissipation factor (tan δ) may increase, or the characteristic may be deteriorated.Use cream solder with halogen
content or 0.1 wt,% or less.
・ When washing right after soldering, make sure the capacitor surface temperature is lower than 60 ℃.
・ The maximum temperature reached on the element surface in reflow is as follows. If a higher temperature is applied,

The moisture-proof packaging is made ECWU and ECPU. When that’s opened, a capacitor absorbs moisture,
and soldering heat-resistance falls to a low level. Please confirm the notice after opening. The notice in detail has
decided on Approval Specification.
1.4 When using soldering iron
With a soldering iron, high temperature is directly applied to the film chip capacitor. Abide by the following soldering
iron conditions, and strictly control the iron tip temperature.
1.4-1 Soldering conditions when using soldering iron.
Observe the following cautions, and use within the soldering conditions next page.
1.4-2 Cautions for use of soldering iron
・ Be careful that the soldering irons do not directly touch the main body of the film chip capacitor. In particular, don’t
touch the side (cut section). If touched by the heated soldering iron, lowering of insulation resistance, shortcircuit
or other characteristic deterioration may occur.
・ Preheat the printed wining board land sufficiently withthe soldering iron, and then solder. Solder without directly
touching the iron tip to the electrode of the capacitor.
・ Don’t reuse the products once removed by the soldering irons.
・ Should not mount the film chip capacitors in the mass production by soldering iron.
(The temperature control is difficult, and the characteristics may be deteriorated.)

2. Washing the mounted boards
Since the film chip capacitor does not have a coating, components of flux or detergent left over on the element at the time
of washing may be activated and invade into the inside of the capacitor, and adverse effects may be caused. Observe the
following cautions.
・ In the case of ultrasonic washing, note that peeling of protective film, electrode separation due to resonance, or
characteristic deterioration may occur depending on the detergent used or ultrasonic output. Check carefully
beforehand.
<CFC substiture detergent>
As a result of regulation of CFC and chlorine derivative detergents, many substitute detergents come to be used,
but the performance of the film chip capacitor may be reduced depending on the type of detergent or washing
condition. Check sufficiently beforehand. Consult us in advance if planning to use CFC substitute detergent.
When using a CFC substitute detergent, with the washing method of spraying detergent (rinsing water)to the
substrate at high pressure, the protective filmon the element surface may be peeled off due to the water pressure.
Check carefully beforehand.
<Drying after washing>
Dry after washing so that the detergent is not left over. If drying is insufficient, the detergent is left over on the
element surface, and the insulation resistance is measured to be lowered. Dry enough so as not to leave
detergent.
