電(dian)(dian)源(yuan)濾波(bo)(bo)(bo)器（英(ying)語(yu)：line filter）或噪聲濾波(bo)(bo)(bo)器（英(ying)語(yu)：noise filter）是(shi)指一(yi)種(zhong)安裝在電(dian)(dian)子設(she)(she)備和(he)其(qi)電(dian)(dian)源(yuan)之間(jian)的(de)電(dian)(dian)子濾波(bo)(bo)(bo)器，其(qi)目的(de)是(shi)在降低設(she)(she)備和(he)電(dian)(dian)源(yuan)之間(jian)電(dian)(dian)源(yuan)線上傳導的(de)電(dian)(dian)磁(ci)干(gan)擾(rao)，電(dian)(dian)磁(ci)干(gan)擾(rao)的(de)信號(hao)一(yi)般(ban)都是(shi)高(gao)頻的(de)信號(hao)，因(yin)此使用的(de)電(dian)(dian)源(yuan)濾波(bo)(bo)(bo)器是(shi)一(yi)種(zhong)低通濾波(bo)(bo)(bo)器，多半是(shi)由電(dian)(dian)容器及電(dian)(dian)感器所組成。

電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)濾(lv)(lv)波(bo)器(qi)(qi)可(ke)(ke)(ke)以(yi)貼裝(zhuang)在(zai)印刷電(dian)(dian)(dian)(dian)(dian)(dian)路板上(shang)，也可(ke)(ke)(ke)以(yi)是(shi)一個安裝(zhuang)在(zai)設備內的獨立元(yuan)件，也有些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)濾(lv)(lv)波(bo)器(qi)(qi)會安裝(zhuang)在(zai)房間或配電(dian)(dian)(dian)(dian)(dian)(dian)盤的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)側。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)濾(lv)(lv)波(bo)器(qi)(qi)可(ke)(ke)(ke)以(yi)整合在(zai)連接(jie)器(qi)(qi)內，例如(ru)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)濾(lv)(lv)波(bo)器(qi)(qi)可(ke)(ke)(ke)以(yi)整合在(zai)模組(zu)化的IEC電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)接(jie)頭，或是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸入模塊中，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)話線(xian)上(shang)的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)濾(lv)(lv)波(bo)器(qi)(qi)可(ke)(ke)(ke)以(yi)整合在(zai)RJ11接(jie)頭中。
