Ferrite toroids
More informations
These Amidon 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.
