avx鉭電(dian)(dian)(dian)容(rong)(rong)跟著溫度的(de)升高,載(zai)流子數(shu)量(liang)增(zeng)加,所以電(dian)(dian)(dian)阻值降低.電(dian)(dian)(dian)容(rong)(rong)是電(dian)(dian)(dian)子設備中大(da)量(liang)運用的(de)電(dian)(dian)(dian)子元件之(zhi)一(yi),廣(guang)泛應用于隔直,耦合(he), 旁(pang)路(lu),濾(lv)波,調諧回路(lu), 轉(zhuan)化,控(kong)制(zhi)電(dian)(dian)(dian)路(lu)等方面。線(xian)繞瓷介微調電(dian)(dian)(dian)容(rong)(rong)器是拆(chai)銅絲外電(dian)(dian)(dian)來變(bian)動電(dian)(dian)(dian)容(rong)(rong)量(liang)的(de),故(gu)容(rong)(rong)量(liang)只能變(bian)小(xiao),不適合(he)在需(xu)反復調試的(de)場合(he)運用,avx鉭電(dian)(dian)(dian)容(rong)(rong)的(de)類型一(yi)般(ban)由(you)四部(bu)分(fen)組成不合(he)用于壓敏、可變(bian)、真(zhen)空(kong)電(dian)(dian)(dian)容(rong)(rong)器。

avx鉭電(dian)容是(shi)(shi)一種(zhong)典型具有(you)溫度(du)性(xing)的半(ban)導(dao)(dao)體(ti)電(dian)阻,它的電(dian)阻值跟著溫度(du)的升(sheng)高(gao)呈(cheng)階躍性(xing)的減小.熱敏(min)電(dian)阻是(shi)(shi)以錳(meng)、鈷(gu)、鎳和銅等(deng)(deng)金屬氧化物為主(zhu)要資(zi)料,avx鉭電(dian)容在(zai)選用(yong)陶瓷工藝制造而(er)成的.這些(xie)金屬氧化物資(zi)料都(dou)具有(you)半(ban)導(dao)(dao)體(ti)性(xing)質(zhi),由于在(zai)導(dao)(dao)電(dian)方式(shi)上完全類似(si)鍺、硅等(deng)(deng)半(ban)導(dao)(dao)體(ti)資(zi)料.溫度(du)低時,這些(xie)氧化物資(zi)料的載流(liu)子電(dian)子和數量少,所以其電(dian)阻值較(jiao)高(gao);
