Paper and plastic film capacitors are subject to two classic failure modes: opens or shorts. Included in these categories are intermittent opens, shorts or high resistance shorts. In addition to these failures, capacitors may fail due to capacitance drift, instability with temperature, high dissipation factor or low insulation resistance.
While the impacts of voltage, current, and temperature on the degradation of DC film capacitors are well investigated, there is still a lack of quantitative study on the impact of humidity. The testing procedures of film capacitors under humidity conditions vary among capacitor manufacturers.
The film/foil variants of plastic film capacitors are especially capable of handling high and very high current surges. Typical capacitance values of smaller film capacitors used in electronics start around 100 picofarads and extend upwards to microfarads.
The "film capacitors" were developed together with the growing market of broadcast and electronic equipment technology in the mid-20th century. These capacitors are standardized under the rules of IEC/EN 60384-1 "Capacitors for use in electronic equipment" and different "film materials" have their own sub standards, the IEC/EN 60384- n series.
The dissipation factor of PP film capacitors is smaller than that of other film capacitors.
In , the accelerated testing designed for metallized film capacitors is under high ripple current and voltage stress conditions. While the impacts of voltage, current, and temperature on the degradation of DC film capacitors are well investigated, there is still a lack of quantitative study on the impact of humidity.
