T37-10 Iron Powder Toroidal Core

The T37-10 is a small toroidal core made from Mix 10 carbonyl iron powder, developed for high-frequency applications. It is a suitable option for building inductors, RF transformers, and other compatible electronic projects where compact size and good performance at higher frequencies are important.

This model has an initial permeability µi of 6, an AL value of 26 µH at 100 turns, and a stated frequency range of 15 to 100 MHz. Its dimensions are 9.53 mm outer diameter, 5.21 mm inner diameter, and 3.25 mm height, with an approximate weight of 1 g.

Mix 10 material is designed to provide high Q up to 150 MHz, and is also described as suitable for cable television applications and moderate band transformers from 400 to 700 MHz. The stated color code for this core is black/clear.
