Very effective at suppressing common mode noise in the 1 to 30MHz region if the cable to be suppressed can be wound through the core a number of times. Ideal for use on RG58 / LL195 and 195 series cables. Also ideal for use on IEC power cables to suppress noise in the HF bands from computer display monitors.

Usable frequency ranges, depending on the application:

RFI / EMI / CMC suppression: 25-300 MHz
