Common mode choke

31 Material is a very good wide band common mode suppression solution in the frequency range from 1 up to 50 MHz. If you use multiple cable turns around the ring core, the suppression will increase while the frequency will decrees. See the following picture to see the effect of multiple turns.

FT240-31 Impedance

Wide band transformer

The 31 ferrite material design is perfect for common mode suppression. The 31 Material is excellent to create a 1:1 balun in the lower frequency range 1 – 10 MHz.  For impedance transformers please use the 43 material.
