42、relates to passive filter units for electromagnetic interference sup-pression 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 construct

43、ed 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

44、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 s

45、upplies) 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 spe
