COMMERCIAL ITEM DESCRIPTION
FILTER, RADIO FREQUENCY INTERFERENCE
The General Services Administration has authorized the use
of this commercial item description (CID) for all federal agencies.
1. SCOPE. This CID covers the general requirements for radio frequency interference (RFI) suppression power line
filters. These filters consist of capacitors and inductors used in combination with each other and are provided with
resistors as a safety feature. This series of RFI filters incorporate the special international Electrotechnical
Commission (IEC) power line connector. Filters covered by this CID are intended for commercial/industrial
applications and should not be used in military systems needing stringent environmental and electrical requirements.
2. CLASSIFICATION. This CID uses a classification system which is included in the Part Identification Number
(PIN) as shown in the following example (see 7.1).
