The FQA series offers high differential and common-mode noise attenuation to simplify system-level compliance to MIL-STD-461G standards.

SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the FQA series of electromagnetic compatibility (EMC) filters for demanding applications in harsh environments such as military vehicles and aircraft.

The EMC filters have a rating of plus-or-minus 40 volts DC at 20 amps, and come in rugged encapsulated quarter-brick packages with a choice of flanged or non-flanged base plates.

The FQA series offers high differential and common-mode noise attenuation to simplify system-level compliance to MIL-STD-461G standards. The modules also provide input spike protection to MIL-STD-1275D and RTCA/DO-160G, and have testing consistent with MIL-STD-883F and MIL-STD-202G.

The circuit-board-mount FQA power electronics device can be cooled using either an industry standard quarter-brick heatsink, or conduction cooled via a cold plate. The non-flanged package size measures 60.6 by 39 by 12.7 millimeters, and the flanged version measures 60.6 by 55.9 by 12.7 millimeters. The total DC resistance of the filter is typically 12 Ohms minimizing power losses.

The filters are available with standard production screening (-S suffix) and a baseplate temperature rating of -40 to 115 degrees Celsius, or with enhanced screening (-M suffix) and an extended temperature rating of -55 to 115 C. Enhanced screening includes functional testing at high and low temperatures and a 96 hour burn-in period with temperature cycling.

All models are safety certified to UL 60950-1, CAN/CSA C22.2 No. 60950-1-07 and IEC 60950-1, IEC/UL/CSA 62368-1 (pending) and carry the CE mark.
