1. Product Introduction of Adjustable Inductance
Adjustable Inductance introduction:General I.F. Adjustable Inductors changes the inductance of the coil by changing the relative position of the permanent magnet and the coil, so as to achieve the purpose of linear compensation. There are usually two ways to change the inductance. 1：The soft ferrite with thread is used to change the position of the iron core in the coil; 2：A sliding switch is used to change the number of coil turns, so as to change the inductance of the inductor.
