Soft ferrite material mainly includes MnZn, NiZn as well as MgZn magnets material.MnZn soft ferrites have the following strong points: suitable in the situation of frequency below 1 MHz, high ui, low loss and high stable characters.
Compared with MnZn soft ferrite magnets, NiZn soft ferrite magnets are used for application between 1MHz and 100MHz frenquece.
Unimagnet owns an experienced and talented team of NiZn soft ferrite magnets, our tightly quality control conception is practiced in every section. Being ahead of the industry field and keeping considerable competitve price are our objective.
The characters of NiZn soft ferrite material are:
High electric resistivity;
high curie temperature;
high Bs,high Ui;
lower coercive force;
low temperature coefficient;
low loss;
