This part of IEC 60384 applies to fixed direct current capacitors, for rated voltages not exceeding 6 300 V, using as dielectric a polyethylene-terephthalate film and electrodes of thin metal foils. For capacitors with rated voltages exceeding 1 000 V, additional tests and requirements may be specified in the detail specification. The capacitors covered by this standard are intended for use in electronic equipment. NOTE Capacitors for radio interference suppression are not included, but are covered by IEC 60384-14 (see bibliography).
