熔(rong)斷(duan)(duan)電(dian)(dian)(dian)阻(zu)器(qi)，是一種(zhong)具有電(dian)(dian)(dian)阻(zu)器(qi)和(he)熔(rong)斷(duan)(duan)器(qi)雙重作用(yong)(yong)的特殊元(yuan)件。它在(zai)電(dian)(dian)(dian)路(lu)中(zhong)用(yong)(yong)字母“RF”或(huo)“R”表(biao)示。熔(rong)斷(duan)(duan)電(dian)(dian)(dian)阻(zu)器(qi)主要應用(yong)(yong)于彩色電(dian)(dian)(dian)視機(ji)、錄像機(ji)及檢測儀表(biao)的電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)路(lu)，彩色電(dian)(dian)(dian)視機(ji)的 行(xing)掃描及場掃描電(dian)(dian)(dian)路(lu)。

熔(rong)斷(duan)電(dian)阻(zu)(zu)器(qi)具(ju)有(you)保護功能(neng)的電(dian)阻(zu)(zu)器(qi)。選(xuan)用(yong)時應考慮其雙重性能(neng)，根據(ju)電(dian)路的具(ju)體要求選(xuan)擇其阻(zu)(zu)值和功率等參數。既要保證它(ta)在過負荷(he)時能(neng)快(kuai)速熔(rong)斷(duan)，又要保證它(ta)在正常條件下能(neng)長期穩定的工作。電(dian)阻(zu)(zu)值過大(da)或功率過大(da)，均不能(neng)起到保護作用(yong)。
