TDK Corp. has introduced the DC input TDK-Lambda RDEN-048050 EMC filter to complement the existing R series of AC input EMC filters. The RDEN-048050 filter can accept an input voltage of up to 76V DC, and is rated for currents up to 50 A.
Enclosed in a metal case, connections are made via rugged M5 studs for easy termination and the filter will operate at 50 A in an ambient of -30 to 55 °C, derating to 20 A at 85 °C. With frequencies between 0.2 to 10 MHz, common mode attenuation is 30 dB and with frequencies between 0.7 to 30MHz differential mode attenuation is 25 dB.
Input to case (ground) isolation is 1,500 VDC and isolation resistance is 500 MW at 500 VDC. The filter is certified to UL60950-1 and EN60939. The package size, excluding terminals, is just 90 mm in depth, 60 mm wide and 30 mm highhttp://www.tdk-lambda
