電(dian)(dian)(dian)容(rong)(rong)是表征電(dian)(dian)(dian)容(rong)(rong)器容(rong)(rong)納(na)電(dian)(dian)(dian)荷(he)本領的物理量。我們(men)把電(dian)(dian)(dian)容(rong)(rong)器的兩極板間的電(dian)(dian)(dian)勢差增加1伏所需的電(dian)(dian)(dian)量，叫做電(dian)(dian)(dian)容(rong)(rong)器的電(dian)(dian)(dian)容(rong)(rong)。電(dian)(dian)(dian)容(rong)(rong)主(zhu)要應用于(yu)電(dian)(dian)(dian)源濾(lv)波、信(xin)號濾(lv)波、信(xin)號耦合、諧振、隔直流等(deng)電(dian)(dian)(dian)路(lu)中。同時電(dian)(dian)(dian)容(rong)(rong)也是中最(zui)常見的(de)元器件之一(yi)。今天飛天鷹科技就來和大(da)家講一(yi)下(xia)電容的(de)相關知識。

               

電(dian)容的種類包括：瓷(ci)片(pian)電(dian)容、高(gao)壓瓷(ci)片(pian)電(dian)容、聚(ju)酯電(dian)容、積層陶瓷(ci)電(dian)容、貼(tie)片(pian)坦(tan)電(dian)容、貼(tie)片(pian)電(dian)解電(dian)容等

電容器(qi)的主要參數(shu)和應(ying)用：

標稱(cheng)電容量(liang)：電容器產品標出的(de)電容量(liang)值。

類(lei)別(bie)溫(wen)(wen)(wen)(wen)度(du)范圍(wei)電(dian)容器設計(ji)所確定(ding)(ding)的能連(lian)續(xu)工作的環境溫(wen)(wen)(wen)(wen)度(du)范圍(wei)，該范圍(wei)取(qu)決于它相應類(lei)別(bie)的溫(wen)(wen)(wen)(wen)度(du)極限(xian)值，如(ru)上限(xian)類(lei)別(bie)溫(wen)(wen)(wen)(wen)度(du)、下限(xian)類(lei)別(bie)溫(wen)(wen)(wen)(wen)度(du)、額定(ding)(ding)溫(wen)(wen)(wen)(wen)度(du)(可以連(lian)續(xu)施加(jia)額定(ding)(ding)電(dian)壓(ya)的最高(gao)環境溫(wen)(wen)(wen)(wen)度(du))等。

額定電(dian)壓（UR）在(zai)下(xia)限類別溫度和額定溫度之間的任一溫度下(xia)，可以(yi)連續施加在(zai)電(dian)容(rong)器上的最大直流(liu)電(dian)壓或最大交流(liu)電(dian)壓的有效值(zhi)或脈沖(chong)電(dian)壓的峰值(zhi)。

損(sun)耗角正(zheng)切（tanδ）在規定頻率的正(zheng)弦(xian)電壓下(xia)，電容器(qi)的損(sun)耗功率除以電容器(qi)的無功功率。

從去(qu)年開始電容器(qi)一(yi)直(zhi)處于缺(que)貨的狀態中(zhong)，價(jia)格(ge)也(ye)一(yi)直(zhi)在(zai)上漲。許多規模較小的電源廠，都因為原材(cai)料不足而停產了(le)，這里飛天鷹科技要感謝哪些一(yi)直(zhi)支持我(wo)們(men)(men)的供應商們(men)(men)，給與了(le)我(wo)們(men)(men)很大的幫(bang)助。
