Car audio amorphous choke core

Car audio amorphous choke core

Using amorphous tape to wind the magnetic core has high saturation magnetic induction intensity. By adopting a specific heat treatment process, it is made to have constant magnetic conductivity within a certain frequency range.


Performance characteristics:

(1) Non gap amorphous inductors have high saturation magnetization, low coercivity, and a wide range of constant magnetic fields;
(2) Eliminating leakage interference caused by amorphous notch magnetic cores;
(3) Good frequency characteristics and low magnetic core losses;
(4) Low cost and low price.


Application areas:

Mainly used for EMC car audio anti-interference, PFC, differential mode filter and smooth output filter
