Product Description
The TDK-Lambda RSEN-2003 is a single-phase EMC/EMI power line filter rated at 3 amps and 250VAC/250VDC, designed to suppress conducted electromagnetic interference on AC or DC power lines. It features an integrated terminal block connection, a compact low-profile chassis-mount enclosure (with optional DIN rail mount via -D suffix), and uses TDK ferrite core material for broadband noise attenuation across a wide frequency range. Rated for up to 750W, the RSEN series is suitable for general-purpose industrial, medical, test, and communications applications requiring compliance with CISPR and related EMC standards.
