• FT240-43 Ferrite Toroid ui=800

Fair-Rite 5943003801 MnZn Ferrite Toroid, 43 material, for EMI suppression between 20 and 250MHz, and wideband transformers up to 50MHz.  ui=800.  These are ideal for use as noise or common mode suppressors on cables to reduce interference on the HF bands, or constructing baluns.  These are recommended for use on HDMI cables where the cable connects to the computer video card to suppress noise in the 3 to 20MHz bands.  It is recommended that two FT240-43 are stacked for use as a 49:1 Transformer for higher efficiency, see End fed half wave antennas by Steve K1RF on how to make a 49:1 Transformer.
