适用范围：1.1 This standard ( Part I) covers the requirements for fixed dc capacitors containing a dielectric of polystyrene film, intended for use in telecommunication equipment and in electronic devices employing similar techniques, but excluding capacitors for a reactive power exceeding 200 VAr.1.2 The electrodes are either thin metal foils or thin layers of metal deposited on the dielectric. In the latter case, the capacitors shall exhibit no self-healing breakdown in the endurance test.1.3 Capacitors for radio interference suppression are not included in this standard, but covered by IS : 3723 ( Part I )-1978〓.
