This generic specification relates to passive filter units for electromagnetic interference suppression
for use within, or associated with, electronic or electrical equipment and machines.
Both single and multi-channel filters within one enclosure are included within the scope of this
generic specification.
Filters constructed of capacitive elements where the inductance is inherent in the construction
of the filter are within the scope of this specification. Similarly, filters constructed of inductive
elements where the capacitance is inherent in the construction of the filter are also within the
scope of this generic specification. The manufacturer should state whether a given component
is to be designed as a capacitor, an inductor or a filter.
The filter units within the scope of this generic specification are further distinguished as those
for which safety tests are appropriate (e.g. those connected to mains supplies) and those for
which such tests are not appropriate. A separate sectional specification covers the passive
filter units for which safety tests are appropriate.
This generic specification establishes standard terms, inspection procedures and methods of
test for use in sectional and detail specifications within the IECQ-CECC system for electronic
components.
