Usable frequency ranges, depending on the application:

broadband transformers: 5 – 400 MHz

high-Q inductors: 0.5 – 30 MHz

RFI / EMI / CMC suppression: 5 – 500 MHz


✔️ common mode shocks (CMC): material 43 it is a very good solution for suppressing common broadband currents in the range of 10 – 600 MHz. Along with the increase no. of turns, the suppression increases, while the max. usable freq. will decrease.

✔️ broadband transformers: excellent impedance transformers can be made in the frequency range from 2 to 50 MHz Typical applications are impedance transformers for EndFed antennas, impedance transformers for OCFD antennas or BalUn 1: 1.
