EMC-Filter CNW 101

Single-phase mains filters (2 lines, single-stage)


Recommended filter for suppressing interference according to EN 55011, Class A and EN 61800-3, category C2.

Low-cost filter with small dimensions and good damping performance for the direct installation in a case on the interference source. The filter is also as a version with low leakage current as well as special medical version (no Y capacitors) available.

Optionally, the filter can be delivered with overvoltage protection. The connection with insulated spade connections enables a fast and touch-proof assembly. Also other versions with different connections (like clamp or braid) are possible.


  • compact construction
  • easy installation
  • touch-proof if used with insulated spade connectors
  • good damping performance at a low leakage current
  • also available as a medical version or with a lower leakage current
  • optional with overvoltage protection
  • UL approval for the complete model range – E217177 (not for N- and MED-versions)

Typical applications

Switch-mode power supplies for industrial electronics, telecommunications, data systems engineering and DC applications.
