Tekst fra IEC om Capacitors and resistors for electronic equipment
To prepare international standards for :
a) Capacitors and resistors intended for use in equipment for telecommunication and electronic devices employing similar techniques.
b) Capacitors, resistors and inductors for radio interference suppression and complete radio interference suppression filter units (see note).
c) Passive integrated circuits or networks containing resistors or capacitors or their combinations. For the dimensional standardization of the final package, requirements laid down by TC 47 shall be adopted whenever possible.
Note : In this work, use is to be made as far as possible of any relevant work of TC 51 on inductors, and of the CISPR on the measurement of radio interference suppression characteristics. Liaison is also to be maintained with TC 61 and other appropriate IEC Technical Committee on the safety aspects of Radio interference suppression components and filter units.
