Base Magnetic Ring Common Mode Inductance

BASE magnetic ring common mode inductance we provide are mainly used for EMI noise suppression of AC power supply, Can eliminate low frequency common mode noise, Has good attenuation characteristics ,It uses less raw materials and less energy.
Product Description

1. Product Introduction of Base Magnetic Ring Common Mode Inductance

In order to ensure the high performance of military power supply, the selected magnetic materials of this BASE magnetic ring common mode inductance are generally ferrite and ferrosilicon aluminum. Because enerally ferrite and ferrosilicon aluminumhave relatively stable performance, little change with temperature and high air gap strength, it is very suitable for military power supply.
