電(dian)(dian)子(zi)(zi)元器(qi)(qi)(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)包括：電(dian)(dian)阻、電(dian)(dian)容器(qi)(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)位器(qi)(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)子(zi)(zi)管(guan)、散熱(re)器(qi)(qi)(qi)(qi)(qi)(qi)、機電(dian)(dian)元件(jian)(jian)(jian)(jian)、連接(jie)器(qi)(qi)(qi)(qi)(qi)(qi)、半導體(ti)分(fen)立器(qi)(qi)(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)、電(dian)(dian)聲器(qi)(qi)(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)、激光器(qi)(qi)(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)、電(dian)(dian)子(zi)(zi)顯示(shi)器(qi)(qi)(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)、光電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)件(jian)(jian)(jian)(jian)、傳(chuan)感器(qi)(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)源、開關、微特電(dian)(dian)機、電(dian)(dian)子(zi)(zi)變壓器(qi)(qi)(qi)(qi)(qi)(qi)、繼電(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)、印制電(dian)(dian)路(lu)板(ban)(ban)、集成電(dian)(dian)路(lu)、各(ge)類電(dian)(dian)路(lu)、壓電(dian)(dian)、晶體(ti)、石英、陶瓷磁性材(cai)料、印刷電(dian)(dian)路(lu)用(yong)基材(cai)基板(ban)(ban)、電(dian)(dian)子(zi)(zi)功能工(gong)藝專(zhuan)用(yong)材(cai)料、電(dian)(dian)子(zi)(zi)膠（帶）制品(pin)、電(dian)(dian)子(zi)(zi)化學材(cai)料及部(bu)品(pin)等。

電子元件符號認識

電(dian)子元件有許多種，為(wei)了區分(fen)一般用“字(zi)(zi)母+數(shu)字(zi)(zi)”的形(xing)式表(biao)(biao)示(shi)(shi)。電(dian)阻用“R+數(shu)字(zi)(zi)”表(biao)(biao)示(shi)(shi)，電(dian)容(rong)用“C+數(shu)字(zi)(zi)”表(biao)(biao)示(shi)(shi)，電(dian)容(rong)容(rong)量誤差表(biao)(biao)符號為(wei)F、G、J、K、L、M，晶(jing)體二極管用“D+數(shu)字(zi)(zi)”表(biao)(biao)示(shi)(shi)，穩壓(ya)二極管用“ZD+數(shu)字(zi)(zi)”表(biao)(biao)示(shi)(shi)，電(dian)感用“L+數(shu)字(zi)(zi)”表(biao)(biao)示(shi)(shi)，晶(jing)體三極管用“Q+數(shu)字(zi)(zi)”表(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(cai)能(neng)保障產品的質量(liang)。此(ci)外要(yao)考(kao)慮電子元件(jian)的型號(hao)細節部分，如產品的誤差、材(cai)質等。最后需要(yao)控制成本，考(kao)慮性價比方面(mian)的需求(qiu)，切勿(wu)貪(tan)小便(bian)宜，可以先(xian)小批(pi)量(liang)采樣再(zai)大規(gui)模采購。

電子元件的作用

1、繼(ji)電(dian)(dian)器(qi)：在(zai)電(dian)(dian)路中起著(zhu)自動調(diao)節、安(an)全保護(hu)、轉換電(dian)(dian)路等作用。

2、電容器：應用于隔直，耦(ou)合，旁路，濾(lv)波，調諧回路， 能量轉換(huan)，控制電路等方面(mian)。

3、連(lian)接器：連(lian)接兩個有源器件(jian)的器件(jian)，傳輸電流或(huo)信號。

4、電位(wei)器：用(yong)于分壓的可變(bian)電阻器。
