Soft Ferrite Core

Nizn Core

Nizn ferrite material have the advantage of high resistivity,high curie temperature,low temperature factor,low relative loss,good high permeability feature,which be widely used in home communication appliance,computer etc area.we are specialized in exporting the all kind of high performance Nizn series core,Initial permeability begin from 80 to 2000.Practical frequency from 1kHz to 100MHz.
