CURRENT RATING: The filters shall be capable of withstanding 140% of rated current for 15 minutes without any deterioration.
INSERTION LOSS: The filter 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.
FC 00-W: 100dB attenuation from 14 kHz to 10 GHz measured per MIL-STD-220A full load
FC 00-X: 100dB attenuation from 14 kHz to 10 GHz measured per MIL-STD-220A full load. SPECIAL: Measured from 14 kHz to 20 MHz under full load condition with extended range buffer network
HIGHLIGHTS : High reliability. Special design and construction developed for secure communication areas, tempest shielded rooms. Designed for many years of continuous fail free service. All filters are field replaceable. Refer to Accessories Section (Page 21) for Filter Discharge Units FC-10,000 Series Refer to Page 20 for Power Factor Correction Coils.
This series of Power Line Penetration Filters can be mounted through the outer wall of a shielded enclosure. The filters are RFI secure and supplied with threaded nipple. Filters supplied with bleeder resistor to prevent shock hazard.
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
High reliability, units are hermetically sealed; terminals are made of high temperature ceramic; complies with MIL-F-15733, where applicable. For world wide use, these filters are available mounted in (UL) steel plated cabinets with standard knockouts for installation in all types of wiring.
Fil-Coil’s complete line of radio frequency interference filters are designed for the purpose of minimizing conducted and radiated interference from power lines in which they are installed. To assure maximum effectiveness of these filters and to prevent equipment radiation, important precautions must be followed
The RF Filtered and Shielded Circuit Breaker Panel Box shall be designed for the distribution, control and protection of electrical circuits, providing filtering and shielding performance as required to meet Secure Communication Standards specified for DCA Red/Black Engineering-Installation Criteria (U), DCA ENSP-422-5C, DCA CIR C175-6A and others. For FCBP 521 thru 563.
These RF Power Factor Correction Coils are designed for FCL-11, 110, 14, 140, and 112 power line filters where limited generator output requires reduced reactive current. Since screen room filters consist of inductors and capacitors, they apply a fixed reactive load to power lines. Filters which provide high attenuation at low frequencies
