在办公机器和汽车的控制用电源上开关电源和整流器是不可缺少的 ,而压粉铁芯则是其关键构件。压粉铁芯是由软磁粉末与绝缘物的混合物冲压成圆环状的制品 ,多用作电源平滑用扼流圈或升压扼流圈用扼流圈的铁芯。压粉铁芯用软磁粉末主要使用Ｆｅ Ｓｉ Ａｌ系合金 ,当前多用其铸锭
Switching power supplies and rectifiers are indispensable for power control of office machines and automobiles, while dust cores are the key components. Dust core is a mixture of soft magnetic powder and insulation punched into a ring-shaped products, and more for power supply smoothing choke choke choke coil or iron core. The soft magnetic powder for dacron core mainly uses Fe Si Al based alloy, and at present it is mostly used for ingot
