Power Line Filters MTN-N & MTK-F Series

GENERAL

The MTK-N & MTK-F series filters are designed to offer substantial reductions in electromagnetic interference. They are designed and tested to the applicable portions of Military Specification MIL-F-15733 titled “General Specification for Filters and Capacitors, Radio Frequency Interference.” MTK series N & F filters are used in shielded/secrue areas to prevent unwanted RFI/EMC interference.

ELECTRICAL

Insertion Loss: Each filter shall provide an insertion loss of 100db minimum over the entire frequency range when measured in accordance with MIL-STD-220A full load condition.

For MTK-F Series - Insertion loss: 100db from 14 KHz to 10GHz measured in accordance with MIL-STD-220A, load condition 100KHz to 20MHz, and full load measurements from 14 KHz - 100KHz using extended range buffer networks.

For MTK-N Series- Insertion loss: 100 db from 14KHz to 10 GHz measured in accordance with MIL-STD-220AA. load condition from 100KHz to 20 MHz.

Current Rating: Each filter is capable of withstanding 140% of rated current overload for 15 minutes without any deterioration.

Voltage: Each filter is capable of operating continuously at full rated voltage. Each filter is tested at twice rated DC voltage for one minute. The maximum voltage drop for each filter shall be 2 volts.

Safety Discharge
As required, assembled power cabinets shall be provided with a bleeder resistor P/N BR-1 for each circuit.


Harmonic Distortion:  Less than 5%.

Temperature Rise:  Each individual filter shall not exceed a temperature rise of 25ºC. Each assembled power cabinet shall not exceed a temperature rise of 40ºC.


MECHANICAL


Case: The cases of each individual filter shall be made of cold rolled steel, minimum thickness #18 gauge. Each individual filter case is electro-tinned or hot tin dipped. Each unit is filled with a solid potting compound and hermetically sealed. Each individual filter is field replaceable without the use of special tools.

Terminals: The terminals are made of high temperature metalized ceramic. Each terminal is supplied with a flexible insulated wire terminating at a U/L approved flame-retardent plastic stand-off insulator with a hex-head screw. All service connections shall be made at the stand-off insulator.

Potting Compound: The potting compound used in the individual filters conforms to MIL-F-15733, flash
point, paragraph 3.16.

Cabinet Construction: Each cabinet is constructed from cold rolled steel. All seams are welded. The R.F. shield between the dirty and clean side is suitably plated. The filters are mounted to the shield using woven R.F. Gasket. The cover on the clean side chamber is attached with an R.F. Gasket and removable screws with appropriate spacing. All other areas not requiring conductivity are painted.
