电感的(de)主(zhu)要(yao)成(cheng)分：电感器一般由骨(gu)架、绕(rao)(rao)组、屏蔽罩、封装(zhuang)材料、磁(ci)芯(xin)或(huo)(huo)(huo)铁(tie)芯(xin)等(deng)组成(cheng)。骨(gu)架： 骨(gu)架泛指绕(rao)(rao)制线(xian)(xian)(xian)圈(quan)的(de)支架。一些(xie)体积较大(da)的(de)固定式电感器或(huo)(huo)(huo)可调(diao)式电感器（如(ru)振荡(dang)线(xian)(xian)(xian)圈(quan)、阻流圈(quan)等(deng)），大(da)多数是将漆包线(xian)(xian)(xian)（或(huo)(huo)(huo)纱包线(xian)(xian)(xian)）环绕(rao)(rao)在骨(gu)架上，再将磁(ci)心(xin)或(huo)(huo)(huo)铜心(xin)、铁(tie)心(xin)等(deng)装(zhuang)入骨(gu)架的(de)内(nei)腔…
伟(wei)大的数学(xue)(xue)家华罗庚(geng)曾说过(guo)“在寻求真理的长河中(zhong)，唯有学(xue)(xue)习(xi)，不断地学(xue)(xue)习(xi)，勤奋(fen)地学(xue)(xue)习(xi)，有创造性地学(xue)(xue)习(xi)，才(cai)能(neng)越重山跨峻岭。学(xue)(xue)习(xi)唯有学(xue)(xue)习(xi)才(cai)是我们进(jin)步的阶(jie)梯(ti)"，继之前的被动元(yuan)件贴片电(dian)(dian)容，今天要分享的内(nei)容是关于电(dian)(dian)感。电(dian)(dian)感的概念电(dian)(dian)抗器(qi)也(ye)叫电(dian)(dian)感器(qi)，一个导体通电(dian)(dian)时就会…
电(dian)(dian)子变(bian)(bian)压(ya)(ya)器(qi)主要是由高(gao)频变(bian)(bian)压(ya)(ya)器(qi)磁芯(铁芯)与两(liang)个(ge)或两(liang)个(ge)以上的线圈(quan)组成，它们互不改变(bian)(bian)位置，从一个(ge)或两(liang)个(ge)以上的电(dian)(dian)回路中，通过交(jiao)流电(dian)(dian)力(li)借助电(dian)(dian)磁感应作用，转变(bian)(bian)成交(jiao)流电(dian)(dian)压(ya)(ya)及(ji)电(dian)(dian)流。在电(dian)(dian)子线路中起着升压(ya)(ya)、降压(ya)(ya)、隔离、整流、变(bian)(bian)频、倒相、阻抗(kang)匹配、逆变(bian)(bian)、储能、滤波等作用。2…
