TDK Corporation announces the introduction of the TDK-Lambda RGF board-mount electromagnetic interference (EMI) filters. Suitable for power supplies with high input current requirements, these 20 A and filters are designed to provide exceptional differential mode filtering. Leveraging advanced TDK component technology, these modules streamline system-level compliance to CISPR as well as other compliance standards.
The RGF filters are encapsulated for protection in harsh environments, measure 52.8 mm x 35.2 mm x 12.7 mm in size, and feature a robust five-sided metal case. The design includes two threaded and two non-threaded mounting holes, ensuring easy installation and enhanced cooling in both conduction and

When used in conjunction with non-isolated DC-DC converter modules, the filters provide a significant amount of differential mode attenuation over a broad frequency range. This reduces overall system noise and simplifies compliance to typical EMI standards. The input voltage ranges from 0 V to 80 V and withstands input transients of up to 100 V for 100 ms durations.
The operating case temperature is between -40° C to 120° C, with a qualified Thermal Cycling Test (TCT) of 700 cycles, or -40° C to 125° C with a 60° C/minute ramp, and a 30 minute dwell time. The RGF filters are compliant to MIL-STD-810G 516.6 Procedure I & IV for shock and MIL-STD-810G 514.6 Procedure I, Cat 10 for vibration.
