進口150度(du)175度(du)高溫電阻

北京(jing)啟爾特新到一批175度高溫(wen)電(dian)(dian)阻(zu)(zu)，儀(yi)器(qi)155度進(jin)口(kou)電(dian)(dian)阻(zu)(zu)阻(zu)(zu)值(zhi)，國外進(jin)口(kou)，阻(zu)(zu)值(zhi)齊全，精度高，進(jin)口(kou)電(dian)(dian)阻(zu)(zu)，年老(lao)化率低(di)，公司備(bei)有大量現(xian)貨，儀(yi)器(qi)150度進(jin)口(kou)電(dian)(dian)阻(zu)(zu)阻(zu)(zu)值(zhi)，歡迎石(shi)油測井單(dan)位及科研單(dan)位來電(dian)(dian)咨(zi)詢。

標(biao)法電(dian)(dian)阻(zu)的(de)阻(zu)值標(biao)法通常有色環法，數字法。色環法在(zai)一般的(de)的(de)電(dian)(dian)阻(zu)上比較(jiao)(jiao)常見。由于手(shou)機(ji)電(dian)(dian)路中的(de)電(dian)(dian)阻(zu)一般比較(jiao)(jiao)小，很少被(bei)標(biao)上阻(zu)值，即(ji)使(shi)有，一般也采(cai)用數字法，即(ji)：

101——表(biao)(biao)(biao)示(shi)100Ω的(de)(de)電(dian)(dian)阻(zu)； 102——表(biao)(biao)(biao)示(shi)1KΩ的(de)(de)電(dian)(dian)阻(zu)； 103——表(biao)(biao)(biao)示(shi)10KΩ的(de)(de)電(dian)(dian)阻(zu)； 104——表(biao)(biao)(biao)示(shi)100KΩ的(de)(de)電(dian)(dian)阻(zu)； 105——表(biao)(biao)(biao)示(shi)1MΩ的(de)(de)電(dian)(dian)阻(zu)； 106——表(biao)(biao)(biao)示(shi)10MΩ的(de)(de)電(dian)(dian)阻(zu)。

如果一個電阻上標為(wei)223，則(ze)這個電阻為(wei)22KΩ。電阻在(zai)手(shou)機(ji)機(ji)板上一般(ban)的外觀(guan)示(shi)意(yi)圖如圖5所示(shi)，其兩端為(wei)銀白(bai)色，中間大部分為(wei)黑色。

230度高溫引線電阻

北京啟(qi)爾特(te)石油(you)科技新到一批測(ce)井230度(du)(du)高(gao)(gao)溫金屬(shu)膜電(dian)(dian)阻，此電(dian)(dian)阻為軸線引線封裝，具有耐(nai)高(gao)(gao)溫，溫漂小(xiao)，精度(du)(du)高(gao)(gao)等特(te)性，適用(yong)于石油(you)測(ce)井等高(gao)(gao)溫環境下，勘探(tan)155度(du)(du)進口電(dian)(dian)阻阻值(zhi)，歡迎廣大用(yong)戶來電(dian)(dian)咨(zi)詢(xun)。

現實電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)的(de)(de)(de)限制每一(yi)個電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)均(jun)有(you)其(qi)承受的(de)(de)(de)電(dian)(dian)(dian)壓或(huo)電(dian)(dian)(dian)流(liu)的(de)(de)(de)上限（主(zhu)要(yao)取(qu)決于電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)的(de)(de)(de)體積）。如(ru)果(guo)電(dian)(dian)(dian)壓或(huo)電(dian)(dian)(dian)流(liu)超(chao)出了這個范圍，首先電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)的(de)(de)(de)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)值會改(gai)變(bian)（在一(yi)些(xie)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)中可以有(you)劇烈的(de)(de)(de)變(bian)動），繼而令(ling)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)因過熱等情況而損毀。大部份電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)會標示額定(ding)的(de)(de)(de)電(dian)(dian)(dian)功率，另外(wai)(wai)一(yi)些(xie)則會提供(gong)額定(ding)的(de)(de)(de)電(dian)(dian)(dian)流(liu)或(huo)電(dian)(dian)(dian)壓。另外(wai)(wai)，現實的(de)(de)(de)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)本身除電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)外(wai)(wai)，亦擁有(you)微量的(de)(de)(de)電(dian)(dian)(dian)感或(huo)電(dian)(dian)(dian)容，使其(qi)表現與(yu)理(li)想的(de)(de)(de)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)(zu)器(qi)有(you)所差異(yi)。
