RF iron powder toroids



More informations

Micrometals iron powder toroids are often used for high Q narrow-band tuned circuits in the specified frequency or for wide band not tuned circuits on a much larger bandwidth than specified.

The AL value is equal to the inductance value for 100 turns winded on the ferrrite core.
