page 3Ferrite toroids

These Micrometals toroids are often used for broadband not tuned circuits, for example as transformers in Norton circuits, as component for power splitters, dividers or combiners, HF balun, for input or output matching, on HF - VHF power amplifiers, on high impedance IF filters, etc..

Moreover, for their characteristics of medium-high inductance, they are also used to build decoupling choke coils, power supply EMI filters, etc.. because they could reach high inductance values.

Dividers-combiners @ -3 dB with 2 pcs of FT…-43 toroids 1 - 30 MHz high insulation very good return loss

Hybrid @ - 6 dB with 1 pc of FT…-43 toroid 1 - 200 MHz high insulation adequate return loss

Silver plated unipolar wires with teflon insulation useful to build inductances and transformers on toroids are available in "cables" section.
