繞線(xian)磁環電(dian)感線(xian)圈是應用(yong)普及度非常高的(de)一種電(dian)感產(chan)品，那么你知道(dao)它(ta)電(dian)路中究竟(jing)發揮著什么樣(yang)的(de)作用(yong)嗎？本篇我們就來簡單探討一下這個問題吧。

繞線(xian)磁(ci)(ci)環(huan)(huan)(huan)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)是(shi)(shi)由(you)環(huan)(huan)(huan)形(xing)磁(ci)(ci)芯纏繞而(er)成的(de)(de)(de)。繞線(xian)磁(ci)(ci)環(huan)(huan)(huan)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)的(de)(de)(de)電(dian)(dian)(dian)(dian)感(gan)(gan)是(shi)(shi)基于電(dian)(dian)(dian)(dian)線(xian)通過交(jiao)流(liu)電(dian)(dian)(dian)(dian)流(liu)時，電(dian)(dian)(dian)(dian)線(xian)內部周(zhou)圍產生(sheng)交(jiao)變磁(ci)(ci)通。繞線(xian)磁(ci)(ci)環(huan)(huan)(huan)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)一般(ban)用于各種通用電(dian)(dian)(dian)(dian)源。當(dang)電(dian)(dian)(dian)(dian)感(gan)(gan)通過DC電(dian)(dian)(dian)(dian)流(liu)時，周(zhou)圍只有固定的(de)(de)(de)磁(ci)(ci)感(gan)(gan)線(xian)，不(bu)會隨著時間的(de)(de)(de)推移而(er)改變；電(dian)(dian)(dian)(dian)子(zi)產品輻射和泄漏的(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)(ci)波不(bu)僅嚴重(zhong)影(ying)響其他電(dian)(dian)(dian)(dian)子(zi)產品的(de)(de)(de)正常運(yun)行(xing)，造成設備功(gong)能(neng)障礙、傳(chuan)輸(shu)錯誤，而(er)且威(wei)脅著人(ren)類(lei)的(de)(de)(de)健康和安全，危害特別大。因(yin)此，減(jian)少了(le)電(dian)(dian)(dian)(dian)子(zi)設備的(de)(de)(de)干(gan)擾(rao)信號(EMI)已經是(shi)(shi)必須考(kao)慮的(de)(de)(de)因(yin)素了(le)。吸收(shou)磁(ci)(ci)環(huan)(huan)(huan)，又稱鐵氧體磁(ci)(ci)環(huan)(huan)(huan)。

繞(rao)線(xian)磁(ci)環(huan)電(dian)感(gan)線(xian)圈應(ying)用(yong)(yong)(yong)產品相對廣泛(fan)，因為繞(rao)線(xian)磁(ci)環(huan)電(dian)感(gan)線(xian)圈本身使(shi)用(yong)(yong)(yong)的(de)(de)電(dian)流相對較高(gao)，然后電(dian)感(gan)值(zhi)也可(ke)以做(zuo)得很(hen)高(gao)，所以電(dian)路(lu)要求也可(ke)以實現，磁(ci)環(huan)的(de)(de)作(zuo)用(yong)(yong)(yong)：磁(ci)環(huan)在不(bu)同(tong)頻(pin)率下具有不(bu)同(tong)的(de)(de)阻(zu)抗(kang)特性(xing)，一般低(di)頻(pin)阻(zu)抗(kang)很(hen)小，當信號頻(pin)率上(shang)升時(shi)，磁(ci)環(huan)性(xing)能的(de)(de)阻(zu)抗(kang)急劇上(shang)升。使(shi)正常有用(yong)(yong)(yong)的(de)(de)信號通(tong)過(guo)良好，并能很(hen)好地抑(yi)制高(gao)頻(pin)干(gan)擾信號通(tong)過(guo)。同(tong)時(shi)磁(ci)環(huan)電(dian)感(gan)的(de)(de)作(zuo)用(yong)(yong)(yong)還有篩選(xuan)信號、過(guo)濾噪(zao)聲、穩定電(dian)流及致電(dian)磁(ci)波干(gan)擾等(deng)重要的(de)(de)作(zuo)用(yong)(yong)(yong)。可(ke)見繞(rao)線(xian)磁(ci)環(huan)電(dian)感(gan)線(xian)圈在電(dian)路(lu)中(zhong)的(de)(de)作(zuo)用(yong)(yong)(yong)之大。
