International Standards and Conformity Assessment for all electrical, electronic and related technologies

TC 40

Capacitors and resistors for electronic equipment


TC 40 Scope

TC 40

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 inter-

ference 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


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.
