scope:

This standard applies to fixed capacitors with metallized electrodes and polypropylene dielectric for use in electronic equipment. These capacitors may have "self-healing properties" depending on conditions of use. They are mainly intended for use with direct voltage. Capacitors for alternating voltage and pulse applications will be covered by supplements to this document or a separate document. The maximum power to be applied is 500 var at 50 Hz and the maximum peak voltage is 2500 V. Two performance grades of capacitors are covered, Grade 1 for long-life application and Grade 2 for general application. Capacitors for radio interference suppression are not included.
