®PLASTIC FILM CAPACITORS

1 Operation voltageThe plastic film capacitor varies in the maximum applicable voltage depending on the applied voltage waveform, current waveform frequency, ambient temperature (capacitor surface temperature), capacitance value, etc.Be sure to use capacitors within the specified values by checking the voltage waveform, current waveform, and frequency applied to them (In the application of high frequency, the permissible voltage varies with the type of the capacitor.For detail see the specification).2 Operating CurrentThe pulse (or AC) current flowing through the capacitor is expressed as: Ⅰ=C x dV/dt

Due to the fact that dissipation factor of the capacitor will generate the internal heat under the application of high frequency or high pulse current, temperature rise in it will occur and may cause deterioration of with standing voltage, even lead to break down (smoking or firing).Therefore, the safety use of capacitor must be within the rated voltage(or category voltage)and the permissible current.The rated current must be considered by dividing into pulse current (peak current) and continuous current (rms current) depending on the break down mode, and when using, should make sure the both currents are within the permissible values.3 Calculation of rms in various waveformsIn each waveform, calculate the rms value in the following formula.

4 Charging and dischargingBecause the charging and discharging current of capacitor is obtained by the product of voltage rise rate (dV/dt) and capacitance, low voltage charging and discharging may also cause deterioration of capacitor such as shorting and open due to sudden charging and discharging current.When charging and discharging, pass though a resistance of 20Ω/V to 1000Ω/V or more to limit current.When connecting multiple film capacitors in parallel in withstand voltage test or life test, connect a resistance of 20Ω/V to 1000Ω/V or more in series to each capacitor. (For detail see the specification) In additional, capacitors must be discharged with resistor before handling.Because the capacitor hasn't discharge resistor inside, so there is residual but maybe deathful electric energy contained.5 Buzzing noiseAny buzzing noise produced by capacitor is caused by the vibration of the film due to the coulomb force that is generated between the electrodes with opposite poles.If the wave-form with a high distortion rate or frequency is applied across the capacitor, the buzzing noise will become louder.But the buzzing noise is of no damage to capacitor.6 Surface over temperature ∆θcaseWhen continuing current flows through the capacitor, the temperature inside the capacitor will rise, induced by accumulated heat.If the temperature exceeds allowed hot-spot temperature, it might cause a short circuit or fire.The limits described in the catalogue are not exceeded and it's necessary to check the temperature on the capacitor surface when it works.

7 Flame retardationAlthough flame retardation epoxy resin or plastic case is used in the coating or encapsulating of plastic film capacitor, continuous outer high temperature or firing will break the coating layer or plastic case of the capacitor, and may lead to melting and firing of the capacitor element.

8 Humid ambientIf used for a long time in a humid ambient, the capacitor might absorb humidity and oxidize the electrodes causing breakage of the capacitor.If case of AC application, high humidity would increase the corona effect. This phenomenon causes a drop of capacitance and a increase of capacitor losses.9 Storage conditions1) Capacitors may not be stored in corrosive atmospheres, particularly not when chlorides, sulfides, acids, lye, salts, organic solvents or similar substances are present.2) It shouldn't be located in particularly high temperature and high humidity, i t must submit to the fol lowing conditions(unchanging primal package):Temperature : ≦35°CHumidity : ≦80% RH, no dew allowed on the capacitor.Storage time: ≦24 months (from the dale marked on the capacitor's body or the label glued to the package)

2 General Description of Film Capacitors

2-1 Principle of Capacitor ConstructionThe principle construction of a parallel plate capacitor is shown in Fig. 1.When a voltage V is applied between the conducting electrodes placed opposite to each other, a certain amount Q of electric charge proportional to the voltage can be stored on the surfaces of the dielectric.The proportional constant is called capacitance C, designating the ability of a capacitor to store energy in an electric field.

Q=C · VQ: Charge [Coulomb]V: Voltage [Volt]C: Capacitance [Farad]The capacitance C ofcapacitor can be expressedby the following equation:

C[F]=ε0 · ε · A / dε: dielectric constantε0: dielectric constant in vacuum (= 8.85x10-12F/m)A: electrode area [m2]d: electrode distance [m]

The dielectric constant of Polypropylene film is 2.2.Larger capacitances can be obtained by entailing the electrode area A or by reducing the distanced.Table 1 shows the dieiectric constants of typical film dielectrics used in capacitors.In many cases, capacitor names are related to their dielectric material used.

3-30 Self-healing (Only for metallized film capacitor)Process by which the electrical properties of the capacitor, after a local breakdown of the dielectric, are rapidly and essentially restored to the values before the breakdown.The metal coatings of the metallized film, which are vacuum-deposited directly onto the plastic film, have a thickness of only several tens nm.At weak points or impurities in the dielectric, a dielectric breakdown would occur.The energy released by the arc discharge in the breakdown channel is sufficient to totally evaporate the thin metal coating in the vicinity of the channel.The insulated region thus resulting around the former faulty area will cause the capacitor to regain its full operation ability.

3-31 Failure rate λFailure rate refers to the work to a moment has not failed products, at that time, the failure probability of occurrence in a time unit.

λ = r

t: test timen: test numberr: number of failures

4 Expected lifetime of the capacitorThe expected lifetime of the capacitor depends on the applied voltage and the hot spot temperature during operation.For capacitors applied in different situation, the designed average service lifes are different.The capacitors used in DC-Link circuits will have a expected lifetime of probable 100000 hrs at rated voltage and 70t hot spot temperature.

4-1 The hotspot temperature estimationDuring operation, the ripple current flowing through the capacitor will generate heat due to the series resistance (Rs) of the capacitor.Considering the above factors hotspot temperature estimation formula is as follows:

Θhs = ΘA + Ⅰrms x ESR x Rth

Θhs : Hotspot TemperatureΘA : Environment TemperatureⅠrms : Ripple CurrentESR : Equivalent series resistanceRth : Thermal Resistance

4-2 Estimation of lifetime calculationConsidering the fever caused by ripple current, internal resistance (hotspot temperature), as well as the applied voltage, life estimation formula:

L = L0 x ( Ur / U )n x 2(Θ — Θhs) / m

L : The calculation of Lifetime, hrsL0 : Rated Lifetime (100000hrs)U : Working Voltage, VDCUr : Rated Voltage, VDCn : Acceleration Coefficient of Voltage, experienced value: 8-12Θhs : The Actual or Calculated Hotspot Temperature, VCΘ : Rated Hotspot Temperature, 70 °Cm : Acceleration Coefficient of Temperature, experienced value: 7-10

PS: Typically the capacity change rate> ± 3%, determined that product failure

Expected lifetime is a statistical value calculated on the basis of experience and on theoretical evaluations.The above formula only as a theoretical reference.The diagrams should be considered only as a theoretical reference.Please consult our technical department in case of working condition different from the rated ones.
