The standard test is 16 h at upper category temperature. This test determines the suitability of capacitors for use and storage under conditions of high humidity when combined with cyclic temperature changes and, in general, producing condensation on the surface of the capacitor.
The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing. The failure rate is defined as the failure percentage divided by a specified operating period.
Above + 85 °C, but without exceeding the maximum temperature, the rated voltage has to be derated in accordance to the dielectric material used. The test voltage of a capacitor is higher than the rated DC voltage and may only be applied for a limited time.
Film capacitors use PP (polypropylene), PET (polyethylene terephthalate), PPS (polyphenylene sulfide), PEN (polyethylene naphthalate), etc., as dielectric material, having higher insulation resistance compared with ceramic capacitors and aluminum electrolytic capacitors as well as higher capability of retaining stored electricity.
In addition, film capacitors have a smaller loss of electricity when charging/discharging as compared to other types of capacitors. In particular, film capacitors made with PP dielectric material not only operate with very small loss, but also maintain its small loss even with temperature changes. Some capacitors pose polarity.
