電子元件符號認識

電(dian)(dian)子元件有許多種(zhong)，為了區分一般用(yong)(yong)(yong)“字(zi)(zi)母+數(shu)字(zi)(zi)”的形式表(biao)(biao)示。電(dian)(dian)阻用(yong)(yong)(yong)“R+數(shu)字(zi)(zi)”表(biao)(biao)示，電(dian)(dian)容(rong)用(yong)(yong)(yong)“C+數(shu)字(zi)(zi)”表(biao)(biao)示，電(dian)(dian)容(rong)容(rong)量誤(wu)差表(biao)(biao)符號(hao)為F、G、J、K、L、M，晶體二極(ji)管用(yong)(yong)(yong)“D+數(shu)字(zi)(zi)”表(biao)(biao)示，穩壓二極(ji)管用(yong)(yong)(yong)“ZD+數(shu)字(zi)(zi)”表(biao)(biao)示，電(dian)(dian)感用(yong)(yong)(yong)“L+數(shu)字(zi)(zi)”表(biao)(biao)示，晶體三極(ji)管用(yong)(yong)(yong)“Q+數(shu)字(zi)(zi)”表(biao)(biao)示。

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(cai)能保障產(chan)品(pin)的(de)質量。此(ci)外要考(kao)慮(lv)電子元件的(de)型號(hao)細節部分，如產(chan)品(pin)的(de)誤差、材(cai)質等。最后(hou)需(xu)要控(kong)制(zhi)成本，考(kao)慮(lv)性價比方面的(de)需(xu)求，切勿貪小便宜，可以先小批量采(cai)樣再(zai)大規模采(cai)購。

電子元件的作用

1、繼電器：在電路中起(qi)著(zhu)自(zi)動(dong)調節(jie)、安全保護、轉換電路等作用。

2、電容器(qi)：應用于隔直，耦合，旁路(lu)，濾波，調(diao)諧回路(lu)， 能量轉換(huan)，控制電路(lu)等方面(mian)。

3、連接(jie)器：連接(jie)兩個(ge)有源器件的器件，傳輸電流或(huo)信號。

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