style="text-indent:25px">鐵粉芯磁環(huán)：鐵粉芯是磁性材料四氧化三鐵的通俗說法，主要應(yīng)用于電器回路中解決電磁兼容性（EMC）問題。實(shí)際應(yīng)用時(shí)，根據(jù)不同波段下對濾波要求不同會添加各種不同的其他物質(zhì)。早期的磁粉芯是由鐵硅鋁合金磁粉壓制而成的“粘結(jié)”金屬軟磁磁芯。人們常將這種鐵硅鋁磁粉芯稱作“鐵粉芯”。它的典型制備工藝為：用Fe-Si-Al合金磁粉經(jīng)過球磨扁平化處理并用化學(xué)方法進(jìn)行絕緣層包覆，然后添加15wt%左右的粘結(jié)劑，混合均勻后模壓固化，較后經(jīng)熱處理(消除應(yīng)力)而制成產(chǎn)品。這種傳統(tǒng)的“鐵粉芯”產(chǎn)品，主要工作于20kHz～200kHz。由于它們有比在同頻段工作的鐵氧體高得多的飽和磁通密度、直流疊加特性好、磁致伸縮系數(shù)接近于零、工作時(shí)無噪聲、頻率穩(wěn)定性好、性能價(jià)格比高等優(yōu)點(diǎn)，在高頻電子變壓器等電子元件中得到了普遍應(yīng)用。它們的缺點(diǎn)是非磁性填充物不產(chǎn)生磁稀釋，也使得磁通通路不連續(xù)，局部退磁導(dǎo)致了磁導(dǎo)率的降低。磁環(huán)的綜合因子用“CF-3A型磁環(huán)分選儀”測量，激勵(lì)電流設(shè)定為2.5A，頻率40KHz。嘉興按摩器磁環(huán)廠家電話</p><p
