IEC 60384-11-2019 pdf download.Fixed capacitors for use in electronic equipment – Part 1 1 : Sectional specification – Fixed polyethylene-terephthalate film dielectric metal foil DC capacitors.
This part of IEC 60384 is applicable 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 document are intended for use in electronic equipment.
Capacitors for electromagnetic interference suppression are not included, but are covered by IEC 60384-14.
The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1:2016 the appropriate quality assessment procedures, tests arid measuring methods and to give general performance requirements for this type of capacitor. Test seventies and requirements prescribed in detail specifications referring to this sectional specification are of an equal or higher performance level. Lower performance levels are not permitted.
