ELECTRICAL

CURRENT RATING: The filters shall be capable of withstanding 140% of rated current for 15 minutes without any deterioration.

INSERTION LOSS: The HEMP Filters shall provide the specified insertion loss of 80 db minimum over its indicated frequency range when measured in accordance with the applicable MIL-STD-220C 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.

 

OPERATING TEMPERATURE

FILTER ELEMENT: Assembly: from 0°F to 104°F (-18°C to 40°C) at rated voltage and full load operations Components: from 0°F to 150°F (-18°C to 65°C) at rated voltage and full load operation

MECHANICAL

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

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

IMPREGNANT: The impregnant 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.
