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 entirely to inductors intended for use on motor vehicles@ in aircraft or for marine applications.
