Our Filters consist of Low Pass filter circuits, passive components which includes inductors, capacitors, resistors and optional transient suppression devices. Each Filter is manufactured and tested per applicable portions of MIL-PRF-15733. Filter cases 16 gage, CRS, plated or painted finish, and sealed with welded and soldered seams for shielding effectiveness. Discharge resistors are incorporated to eliminate potential shock hazard

Our enclosures are Modified NEMA type fabricated panel of not less than 14 gauge cold rolled steel painted Gray (Std. Paint Color). They include an RF tight inner area secured with RF gasket for 100 dB minimum shielding effectiveness, 14 kHz to 18 GHz, minimum. Front cover allows access to filters and terminal standoffs, with Pre-wired standoffs, lugs and lifting ears included.
