電子元件符號認識

電(dian)子元件(jian)有許多種，為了區(qu)分(fen)一般用(yong)(yong)“字母+數(shu)(shu)字”的(de)形式表(biao)示(shi)。電(dian)阻用(yong)(yong)“R+數(shu)(shu)字”表(biao)示(shi)，電(dian)容用(yong)(yong)“C+數(shu)(shu)字”表(biao)示(shi)，電(dian)容容量誤差表(biao)符號(hao)為F、G、J、K、L、M，晶(jing)體二極管(guan)(guan)用(yong)(yong)“D+數(shu)(shu)字”表(biao)示(shi)，穩壓二極管(guan)(guan)用(yong)(yong)“ZD+數(shu)(shu)字”表(biao)示(shi)，電(dian)感用(yong)(yong)“L+數(shu)(shu)字”表(biao)示(shi)，晶(jing)體三極管(guan)(guan)用(yong)(yong)“Q+數(shu)(shu)字”表(biao)示(shi)。

電子元件采購注意事項

最需要注意的是找正規工商注冊的公司進行采購，了解供應商資質，三證是否齊全，只有優質的電子元件品牌才能保障產(chan)品的(de)(de)(de)質量。此外(wai)要考慮電(dian)子(zi)元件的(de)(de)(de)型號(hao)細節(jie)部分，如產(chan)品的(de)(de)(de)誤差、材質等。最后需要控制成本(ben)，考慮性價(jia)比方面的(de)(de)(de)需求，切勿貪小(xiao)便宜(yi)，可以(yi)先(xian)小(xiao)批量采樣再大(da)規模采購。

電子元件的作用

1、繼電器：在(zai)電路中起(qi)著(zhu)自動(dong)調(diao)節、安全保護、轉換(huan)電路等作(zuo)用。

2、電容器(qi)：應(ying)用于隔直，耦合(he)，旁路，濾波，調(diao)諧回路， 能(neng)量轉(zhuan)換，控制電路等方面。

3、連接器：連接兩個有(you)源器件的器件，傳輸電流(liu)或信(xin)號。

4、電位器(qi)：用于分壓的可變電阻器(qi)。
