電子元件符號認識

電(dian)子元(yuan)件(jian)有(you)許多種，為了區分一般用(yong)“字(zi)(zi)母+數(shu)字(zi)(zi)”的形式表(biao)(biao)(biao)示(shi)(shi)。電(dian)阻用(yong)“R+數(shu)字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，電(dian)容用(yong)“C+數(shu)字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，電(dian)容容量誤差(cha)表(biao)(biao)(biao)符(fu)號為F、G、J、K、L、M，晶體二極(ji)管(guan)用(yong)“D+數(shu)字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，穩壓二極(ji)管(guan)用(yong)“ZD+數(shu)字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，電(dian)感用(yong)“L+數(shu)字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，晶體三極(ji)管(guan)用(yong)“Q+數(shu)字(zi)(zi)”表(biao)(biao)(biao)示(shi)(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品的質量。此(ci)外要考(kao)慮電子元(yuan)件的型號細節部分(fen)，如產品的誤差(cha)、材質等。最(zui)后需(xu)要控制成(cheng)本，考(kao)慮性價比方面的需(xu)求，切勿貪(tan)小便(bian)宜，可(ke)以先小批(pi)量采樣(yang)再(zai)大規模采購。

電子元件的作用

1、繼電(dian)器：在(zai)電(dian)路(lu)中起著(zhu)自動調節、安全保護、轉換電(dian)路(lu)等作用。

2、電容器：應用于隔(ge)直，耦合，旁路，濾波，調諧(xie)回路， 能量轉(zhuan)換(huan)，控制(zhi)電路等方面(mian)。

3、連(lian)接(jie)器：連(lian)接(jie)兩個有源器件(jian)的器件(jian)，傳輸(shu)電流或信(xin)號。

4、電位器：用(yong)于(yu)分壓的可變電阻(zu)器。
