This International Standard applies to inductors designed for electromagnetic interference
suppression intended for use within, or associated with, electronic or electrical equipment and
machines. It is restricted to inductors for which safety tests are appropriate.
The combination of two or more inductors within one enclosure is also included.
Inductors within the scope of this standard may also be used to protect apparatus and
machines from electrical noise and voltage or current transients coming from either the supply
or from other parts of the apparatus.
This standard does not necessarily apply in its entirety to inductors intended for use on motor
vehicles, in aircraft or for marine applications.
