Description
JW MILLER 5248 Bourns / JW Miller Fixed Ferrite Core Inductor 68uH 5A 20% Axial Through Hole
Powdered iron and ferrites are both classified as soft ferrites, but they have very different characteristics, even within the same ‘family’. They are generally unsuitable for low frequency operation, except at low levels. Ferrites are often used as signal transformers (such as isolation transformers for telecommunications or other small signal applications), where the high permeability makes them an ideal choice for small size and high inductance.
Core materials are generally classified as ‘soft’ – this has nothing to do with their physical properties (they are all hard to very hard), but is a reference to their ability to retain magnetism (remanence). Hard magnetic materials are used for magnets, and they have a very high remanence, which is to say they retain a very large proportion of the original magnetic field that was induced into them during manufacture.
