TDK Corporation is introducing the RDEN-048050 48Vdc nominal EMC filter rated at 50A. Enclosed in a compact metal case, the filter utilises stud terminals for ease of connection. Excluding the terminals, the filter measures just 90mm in length, 60mm in width and has a height of 30mm.

Rated for a maximum voltage of 75V DC, the RDEN will operate at full rated current in ambient temperatures of -30 to +55degC, and with derating, up to +85degC at 20A. The RDEN has a differential mode attenuation of 25dB (0.7 to 30MHz), and common mode attenuation of 30dB (0.2 to 10MHz). The isolation voltage from terminals to case is 1500V DC, and has a DC resistance of 3mΩ.

The filter is certified to UL 60950-1, CSA C22.2 No.60950-1 (cUL) and EN 60939, and is compliant with the RoHS Directive.
