電子元件符號認識

電(dian)(dian)子元件(jian)有許多種，為了區分一般用(yong)(yong)(yong)“字(zi)母+數(shu)(shu)字(zi)”的形式(shi)表(biao)示(shi)。電(dian)(dian)阻用(yong)(yong)(yong)“R+數(shu)(shu)字(zi)”表(biao)示(shi)，電(dian)(dian)容(rong)用(yong)(yong)(yong)“C+數(shu)(shu)字(zi)”表(biao)示(shi)，電(dian)(dian)容(rong)容(rong)量誤差表(biao)符(fu)號為F、G、J、K、L、M，晶(jing)體(ti)(ti)二(er)極管用(yong)(yong)(yong)“D+數(shu)(shu)字(zi)”表(biao)示(shi)，穩壓二(er)極管用(yong)(yong)(yong)“ZD+數(shu)(shu)字(zi)”表(biao)示(shi)，電(dian)(dian)感用(yong)(yong)(yong)“L+數(shu)(shu)字(zi)”表(biao)示(shi)，晶(jing)體(ti)(ti)三極管用(yong)(yong)(yong)“Q+數(shu)(shu)字(zi)”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(zhang)產(chan)品的(de)質(zhi)量。此外要考(kao)慮(lv)電子元件的(de)型號細節(jie)部分，如(ru)產(chan)品的(de)誤差、材質(zhi)等(deng)。最后需要控(kong)制成本，考(kao)慮(lv)性價(jia)比方面的(de)需求，切勿貪小便宜，可以先小批量采(cai)樣再大(da)規(gui)模(mo)采(cai)購。

電子元件的作用

1、繼電(dian)器(qi)：在電(dian)路中起著(zhu)自動調節(jie)、安(an)全保護、轉換電(dian)路等作(zuo)用。

2、電容器(qi)：應用(yong)于隔直，耦合，旁路，濾波，調諧回路， 能量轉換，控制電路等方面(mian)。

3、連接器：連接兩個有源器件的器件，傳輸電(dian)流或信號。

4、電(dian)位器(qi)：用于分壓的可變電(dian)阻(zu)器(qi)。
