TDK introduces 20 and 40A, 80Vdc board-mount EMI Filters, reducing differential mode conducted emissions for switching power supplies with high input current requirements.
TDK Corporation announces the introduction of the TDK-Lambda RGF board-mount EMI filters.
Suitable for power supplies with high input current requirements, these 20 and 40A 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 x 35.2 x 12.7mm in size, and feature a robust 5-sided metal case. The design includes two threaded and two non-threaded mounting holes, ensuring easy installation and enhanced cooling in both conduction and convection-cooled systems. Applications include harsh industrial, commercial-off-the-shelf (COTS), test and measurement, communications, broadcast, and robotics.
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 to 80V and withstands input transients of up to 100V for 100ms durations.
The operating case temperature is between -40 to +120oC, with a qualified Thermal Cycling Test (TCT) of 700 cycles, or -40 to +125°C with a 60°C/minute ramp, and a 30minute 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.
