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.
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.
