Spiderbeam FT240-61 MnZn Ferrite Toroid Ring




FT240-61: Original Fair-Rite high quality toroid. These are ideal to construct Baluns for 3 to 50MHz or EMI noise suppression above 200MHz.
Ferrite toroid’s can be used as common mode choke, impedance transformer or balun.
Common mode choke.
61 Material is a good wide band common mode suppression solution in the high frequency range from 25 up to 2000MHz.
If you use multiple cable turns around the ring core, the suppression will increase while the frequency will decrees.
Single turn frequency range 200 – 2000MHz. Multiple turns 25 – 300MHz.
Wide band transformer.
You can make excellent impedance transformers in the frequency range from 15 up to 200 MHz as well.
Typical applications are end fed antenna impedance transformers, off center fed antenna impedance transformers or 1:1 Balun’s.
