電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)是(shi)由電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)和電(dian)(dian)(dian)(dian)(dian)(dian)子元器件組成的(de)(de)(de)，不(bu)同的(de)(de)(de)線(xian)(xian)(xian)路(lu)所(suo)(suo)需求(qiu)的(de)(de)(de)貼(tie)片保(bao)險絲的(de)(de)(de)參(can)數(shu)都(dou)不(bu)盡相同，貼(tie)片電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的(de)(de)(de)主要參(can)數(shu)有電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)、允許(xu)偏差(cha)、分(fen)布(bu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)、額定電(dian)(dian)(dian)(dian)(dian)(dian)流及品質因數(shu)等。1. 電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)的(de)(de)(de)大(da)(da)小，主要取決于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)線(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)圈(quan)(quan)(quan)數(shu)(匝(za)數(shu))，繞制方式，有無(wu)磁(ci)(ci)(ci)心(xin)(xin)(xin)及磁(ci)(ci)(ci)心(xin)(xin)(xin)的(de)(de)(de)材料等決定。通常情況下，線(xian)(xian)(xian)圈(quan)(quan)(quan)圈(quan)(quan)(quan)數(shu)越(yue)(yue)多，繞制的(de)(de)(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)越(yue)(yue)密集，電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)就越(yue)(yue)大(da)(da)。有磁(ci)(ci)(ci)心(xin)(xin)(xin)的(de)(de)(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)比無(wu)磁(ci)(ci)(ci)心(xin)(xin)(xin)的(de)(de)(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)大(da)(da)。磁(ci)(ci)(ci)心(xin)(xin)(xin)導磁(ci)(ci)(ci)率越(yue)(yue)大(da)(da)，電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)也就越(yue)(yue)大(da)(da)。所(suo)(suo)以(yi)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)是(shi)有很(hen)多因素來(lai)決定它(ta)的(de)(de)(de)大(da)(da)小。電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)量(liang)(liang)(liang)的(de)(de)(de)基本單(dan)位(wei)是(shi)亨利(簡稱亨)，用(yong)字母“H”表示。常用(yong)的(de)(de)(de)單(dan)位(wei)還有毫亨(mH)和微亨(μH)，它(ta)們之(zhi)間的(de)(de)(de)關系是(shi)：1H=1000mH;1mH=1000μH2.允許(xu)偏差(cha)標注的(de)(de)(de)感(gan)(gan)(gan)量(liang)(liang)(liang)與實際感(gan)(gan)(gan)量(liang)(liang)(liang)的(de)(de)(de)允許(xu)誤差(cha)值(zhi)。一般用(yong)于(yu)振蕩或(huo)濾波線(xian)(xian)(xian)路(lu)中(zhong)的(de)(de)(de)貼(tie)片電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)要求(qiu)精度較高，允許(xu)偏差(cha)為(wei)±0.2%~±0.5%;而用(yong)于(yu)耦合(he)或(huo)高頻(pin)阻流的(de)(de)(de)精度要求(qiu)不(bu)高，允許(xu)偏差(cha)為(wei)±10%~15%。3.分(fen)布(bu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)線(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)匝(za)與匝(za)之(zhi)間、線(xian)(xian)(xian)圈(quan)(quan)(quan)與磁(ci)(ci)(ci)心(xin)(xin)(xin)之(zhi)間存在的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)。分(fen)布(bu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)越(yue)(yue)小，其(qi)穩(wen)定性越(yue)(yue)好。4.額定電(dian)(dian)(dian)(dian)(dian)(dian)流貼(tie)片電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)正常工作(zuo)時(shi)允許(xu)通過的(de)(de)(de)最(zui)大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)流值(zhi)。若工作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)流超過額定電(dian)(dian)(dian)(dian)(dian)(dian)流，則會燒毀。5.品質因數(shu)也稱Q值(zhi)或(huo)優值(zhi)，是(shi)衡量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器質量(liang)(liang)(liang)的(de)(de)(de)主要參(can)數(shu)。他是(shi)指貼(tie)片電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)在某一頻(pin)率的(de)(de)(de)交流電(dian)(dian)(dian)(dian)(dian)(dian)壓下工作(zuo)時(shi)，所(suo)(suo)呈(cheng)現的(de)(de)(de)感(gan)(gan)(gan)抗與其(qi)等效(xiao)損耗(hao)電(dian)(dian)(dian)(dian)(dian)(dian)阻之(zhi)比。Q值(zhi)越(yue)(yue)高，損耗(hao)越(yue)(yue)小，效(xiao)率越(yue)(yue)高。
