6 FAQs about [Film capacitor loss frequency]

How do you calculate the life of a film capacitor?

For the life of a film capacitor, the Mean Time To Failure(MTTF), which is calculated by the inverse of the failure rate, is used as the basis for the life calculation. If a capacitor is used at high temperatures, its service life will be shortened due to thermal deterioration.

What happens if a metallized film capacitor is over withstand voltage?

*) In case of the metallized film capacitors (evaporated metal electrode type), if voltage in excess of the withstand voltage (or apparently in excess of the withstand voltage due to the lowering of withstand voltage) is applied, self-healing will happen continuously.

Can a stacked film capacitor cause a loss of capacitance?

Since, in principle, a stacked-film capac-itor comprises a large number of independent capacitors in parallel, any contact weakness occur-ring can only affect individual capacitor elements, not extending to neighboring ones, and thus limiting damage to a minor loss of capacitance. Refer to chapter "EMI suppression capacitors" of this data book.

Why are film capacitors used in DC fltering?

Film capacitors are widely used for DC fltering in power supplies. Their function is to smooth out the DC voltage waveform after rectifcation. As with all switching devices, IGBTs are subjected to voltage transients during turn-of operation. Voltage transients result from energy trapped in the circuit’s stray inductance.

How reliable are film capacitors?

The most important reliability feature of film capacitors is their self-healing capability, i.e. their abil-ity to clear faults (such as pores or impurities in the film) under the influence of a voltage. The metal coatings, vacuum-deposited directly onto the plastic film, are only 20 50 nm thick.

Can CDE film capacitors be used with pacitors?

pacitors.AC Voltage Operation:Youcan use all CDE film capacitors with either AC or DC vo tages or a combination of the two. The rules for successful application are: 1) don’t exceed the dielec-tric’s voltage capability; 2) keep the capacitor cool,
