合(he)金(jin)(jin)(jin)電(dian)(dian)阻(zu)(zu)的(de)價格(ge)從幾塊錢/kpcs 到幾十塊錢不等(deng),也是(shi)(shi)按照封裝和精度(du)差異的(de)。合(he)金(jin)(jin)(jin)電(dian)(dian)阻(zu)(zu)的(de)精細(xi)度(du)比厚(hou)膜電(dian)(dian)阻(zu)(zu)精確許多,厚(hou)膜電(dian)(dian)阻(zu)(zu)一般(ban)是(shi)(shi)1%和5%,而合(he)金(jin)(jin)(jin)電(dian)(dian)阻(zu)(zu)能夠到達1%以下.合(he)金(jin)(jin)(jin)電(dian)(dian)阻(zu)(zu)是(shi)(shi)一種選用合(he)金(jin)(jin)(jin)為電(dian)(dian)流介質的(de)電(dian)(dian)阻(zu)(zu),一般(ban)是(shi)(shi)具有(you)低(di)阻(zu)(zu)值,高精細(xi),低(di)溫(wen)度(du)系數,耐(nai)沖(chong)擊電(dian)(dian)流,大功率shu等(deng)特(te)點。在這(zhe)類(lei)電(dian)(dian)阻(zu)(zu)的(de)常見問(wen)題是(shi)(shi)我們可以通過(guo)各類(lei)電(dian)(dian)子產品(pin)得到解答,對于產品(pin)在電(dian)(dian)流上(shang)的(de)采(cai)樣,或短路(lu)保護等(deng)時(shi)運用。合(he)金(jin)(jin)(jin)電(dian)(dian)阻(zu)(zu)是(shi)(shi)貼片式的(de)電(dian)(dian)阻(zu)(zu)。
關于合(he)(he)金(jin)的(de)(de)(de)(de)(de)(de)(de)主要資(zi)料來說(shuo),關于其他的(de)(de)(de)(de)(de)(de)(de)資(zi)料來說(shuo)形成了錳(meng)銅等。在其他輔(fu)助(zhu)資(zi)料傍邊,挑(tiao)選的(de)(de)(de)(de)(de)(de)(de)功能是(shi)(shi)由合(he)(he)金(jin)資(zi)料的(de)(de)(de)(de)(de)(de)(de)本身而決議的(de)(de)(de)(de)(de)(de)(de)。旺詮合(he)(he)金(jin)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)是(shi)(shi)什(shen)么(me)。 就(jiu)是(shi)(shi)導體對電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)(de)(de)阻(zu)(zu)(zu)(zu)止(zhi)效(xiao)果,就(jiu)稱為電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)。 電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)器 就(jiu)是(shi)(shi)不同規(gui)格的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)的(de)(de)(de)(de)(de)(de)(de)產品。電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)一般(ban)用是(shi)(shi)R表明,電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)是(shi)(shi)一個物理位置,在物理學中(zhong)表明導體對電(dian)(dian)(dian)(dian)流阻(zu)(zu)(zu)(zu)止(zhi)效(xiao)果的(de)(de)(de)(de)(de)(de)(de)大小。導體的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)越大,表明導體對電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)(de)(de)阻(zu)(zu)(zu)(zu)止(zhi)效(xiao)果越大。電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)用R表明。
旺詮合金電阻是由導體兩端的電壓與經過導體的電流I的比值來界說,即R=U/I。所以,當導體兩端的電壓一定時,電阻愈大,經過的電流就愈小; 反之,電阻愈小,經過的電流就愈大。不同導體的電阻是按其性質的不同,來決定的,是可以分兩種類型的。
