GENERAL

The filter herein described shall be designed for filtering of radio frequency interference and to meet the requirements of Military Specifications MIL-F-15733, where applicable. These filters may be used with other electrical devices to enable the devices to meet the requirements of MIL-I-26600, MIL-I-16910. MIL-I- 6181, MIL-I-11748, MIL-STD-461, 462, 463, FED-STD-222 and FCC Specification Part 18. Also, DCA specifications and others developed for special equipment and systems applications

 

ELECTRICAL

CURRENT RATING: The filters shall be capable of withstanding 150% of rated current for 15 minutes without any deterioration.

INSERTION LOSS: The filter shall provide the specified insertion loss of 100 db minimum over its indicated frequency range when measured in accordance with the applicable MIL-STD-220A by a government approved laboratory.

VOLTAGE: The filters shall be capable of operating continuously at full- rated voltage and of withstanding an initial voltage test of twice the rated voltage for one minute.

 

MECHANICAL

CASE: The filter case shall be made of cold-rolled steel.

CONSTRUCTION: Input and output terminals shall be completely enclosed in RF shielded compartments. Covers on the input and output RF shielded compartments shall be friction-fitted. Internal components shall be mounted and fixed to prevent damage when subjected to shock and vibration tests.

FINISH: All filter cases shall be made corrosion-resistant with suitable lacquer over primer,  All unfinished grounding surfaces shall be protected by suitable plating.

IMPREGNANT: The impre9nant shall be non-flammable as classified by Underwriters Laboratories.

TERMINALS: The terminals shall be made of high temperature alumina ceramic. The ceramic terminal shall have a flexible insulated lead, one end of which is permanently affixed to the terminal, The other end shall be terminated in a permanently affixed lug which shall be mounted on approved flame-retardant insulator.
