選用(yong)(yong)光(guang)(guang)敏電(dian)阻器(qi)時，應(ying)首先(xian)確(que)定應(ying)用(yong)(yong)電(dian)路中所需光(guang)(guang)敏電(dian)阻器(qi)的(de)光(guang)(guang)譜特(te)性(xing)類(lei)。若(ruo)(ruo)是(shi)用(yong)(yong)于(yu)各種光(guang)(guang)電(dian)自動(dong)控(kong)制系(xi)統、電(dian)子照相機(ji)和光(guang)(guang)報警器(qi)等(deng)電(dian)子產品，則(ze)應(ying)選取(qu)用(yong)(yong)可(ke)見光(guang)(guang)光(guang)(guang)敏電(dian)阻器(qi)；若(ruo)(ruo)是(shi)用(yong)(yong)于(yu)紅外(wai)信號檢(jian)測及天文、軍事等(deng)領域的(de)有關自動(dong)控(kong)制系(xi)統、則(ze)應(ying)選用(yong)(yong)紅外(wai)光(guang)(guang)光(guang)(guang)敏電(dian)阻器(qi)；若(ruo)(ruo)是(shi)用(yong)(yong)于(yu)紫外(wai)線探測等(deng)儀器(qi)中，則(ze)應(ying)選用(yong)(yong)紫外(wai)光(guang)(guang)光(guang)(guang)敏電(dian)阻器(qi)。

選好光(guang)敏(min)電阻(zu)(zu)器的(de)類(lei)型(xing)后，還(huan)應看所選光(guang)敏(min)電阻(zu)(zu)器的(de)主要參數(shu)（包(bao)括亮電阻(zu)(zu)、暗(an)電阻(zu)(zu)、最高工(gong)作電壓、視電流(liu)、暗(an)電流(liu)、額(e)定功率、靈(ling)敏(min)度(du)等）是否符合(he)應用(yong)電路的(de)要求。
