  • Suitable for harsh and demanding environments, including MIL-COTS vehicle and airborne applications

Original Press Release:

20A 40Vdc MIL-COTS EMI Filters Simplify Compliance to MIL-STD-461G, MIL-STD-1275D and RTCA/DO-160G

TDK Corporation announces the introduction of the TDK-Lambda FQA series of EMC filters, with a rating of +/-40Vdc at 20A. The FQA has a rugged encapsulated quarter-brick package with a choice of flanged or non-flanged baseplates. These modules are suitable for use in a wide variety of harsh and demanding environments, including MIL-COTS vehicle and airborne applications.

The FQA series is designed with a high differential and common mode noise attenuation. This simplifies system level compliance to MIL-STD-461G standards. The modules also provide input spike protection to MIL-STD-1275D and RTCA/DO-160G. Qualifying testing is consistent with MIL-STD-883F and MIL-STD-202G.

The PCB mount FQA can be cooled using either an industry standard ¼ brick heatsink, or conduction cooled via a cold plate. The non-flanged package size measures 60.6 x 39 x 12.7mm (L x W x H) and the flanged version 60.6 x 55.9 x 12.7mm. The total DC resistance of the filter is typically 12mΩ, minimizing power losses.

The filters are available with standard production screening (-S suffix) and a baseplate temperature rating of -40°C to +115°C, or with enhanced screening (-M suffix) and an extended temperature rating of -55°C 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 have been 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.
