The T37-0 is a small toroidal core made from non-magnetic phenolic Mix 0 material. This material is designed to provide a stable mechanical form for winding air coils, while also being suitable for RF projects and other high-frequency electronic applications.
This model has an initial permeability µi of 1, an A<sub>L</sub> value of 5 µH at 100 turns, and a stated operating range of 50 to 350 MHz. The core measures 9.53 mm outer diameter, 5.21 mm inner diameter, and 3.25 mm height, with an approximate weight of 1 g.
Mix 0 material stands out for being non-magnetic, non-conductive, and offering excellent temperature stability as well as high Q at very high frequencies. It is also useful for moderate broadband transformers from 600 to 1000 MHz.
