旺詮合金電阻的功用，合金電阻是通過額外電壓、分斷能力等指標來確保的，尤其要通權勢巨擘的第三方安規認證來確保，但電阻式合金電阻本身不是元件，也不需要認證，其性就可想而知，本來維護功用就缺乏，并且在燒斷過程中難以確保不產生危及鄰近的不現象。

旺(wang)(wang)詮合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)的首要(yao)原因(yin)(yin)是(shi)由熔體部分(fen)、支(zhi)架(jia)部分(fen)等三(san)部分(fen)組(zu)成。旺(wang)(wang)詮合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)的負載有(you)必定的限度，也就是(shi)說(shuo)假設流(liu)經電(dian)(dian)(dian)(dian)(dian)阻(zu)的電(dian)(dian)(dian)(dian)(dian)流(liu)超過限度時會把(ba)它燒壞(huai)，使(shi)電(dian)(dian)(dian)(dian)(dian)阻(zu)呈現開路(lu)狀況，從這個意義上來說(shuo)，電(dian)(dian)(dian)(dian)(dian)阻(zu)具有(you)類似合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)的功(gong)用(yong).電(dian)(dian)(dian)(dian)(dian)途經流(liu)時能(neng)夠堵截電(dian)(dian)(dian)(dian)(dian)流(liu)，好象(xiang)能(neng)起到合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)的作用(yong)，因(yin)(yin)此有(you)一部分(fen)廠商為了(le)下(xia)降本錢旺(wang)(wang)詮合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)把(ba)原規劃中的合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)換成廉價的合(he)金(jin)(jin)(jin)電(dian)(dian)(dian)(dian)(dian)阻(zu)電(dian)(dian)(dian)(dian)(dian)阻(zu)，形(xing)式上給客戶增加(jia)一點。
