style="text-indent:25px">使用鐵氧體磁環(huán)規(guī)格注意事項(xiàng)：1.鐵氧體磁環(huán)規(guī)格的效果與電路阻抗有關(guān)：電路的阻抗越低，則鐵氧體磁環(huán)(磁珠)的濾波效果越好。因此，在一般鐵氧體材料的產(chǎn)品手冊(cè)中，并不給出鐵氧體材料的插入損耗，而是給出鐵氧體材料的阻抗，鐵氧體材料的阻抗越大，濾波效果也越好。2.共模扼流圈的匝數(shù)：增加穿過(guò)磁環(huán)的匝數(shù)可以增加低頻的阻抗，但是由于寄生電容增加，高頻的阻抗會(huì)減小。盲目增加匝數(shù)來(lái)增加衰減量是一個(gè)常見(jiàn)的錯(cuò)誤。當(dāng)需要壓制的干擾頻帶較寬時(shí)，可在兩個(gè)磁環(huán)上繞不同的匝數(shù)。紹興無(wú)刷電機(jī)磁環(huán)價(jià)格</p><p
