1-Line Feedthrough Components

TDK 1-Line EMC feedthrough components provide broadband EMI suppression up to the GHz range. The concentric layout of the components enables high insertion loss values to be attained in frequencies up to the GHz range. TDK EMC feedthrough components offer a rated voltage of 250V_AC, 16 to 500A current, and 0.025 to 4.7μF capacitance. Compliant with IEC 60384-14 respectively IEC 60939, the components are well-suited for broadband interference suppression for AC/DC supply lines in e.g. shielded rooms, power supplies, telephone exchanges, base stations, electrical machines, and systems. They are available with threaded studs or axial leads.
