什么情況下該選用什么貫穿電容?
電容是貫穿電容上標注的該電容的各種參數,它的耐壓值與制造時所用的介質材料有關,不同電路中,應選用不同類型的貫穿電容,下面貫穿電容有限公司來給大家說說什么情況下該選用什么貫穿電容。
1、對于電(dian)(dian)(dian)源濾波和(he)放大器中耦合、退(tui)耦電(dian)(dian)(dian)路,電(dian)(dian)(dian)解(jie)貫(guan)穿電(dian)(dian)(dian)容(rong)品(pin)牌,選用電(dian)(dian)(dian)解(jie)貫(guan)穿電(dian)(dian)(dian)容(rong);
 2、對于高頻(pin)電(dian)(dian)(dian)路和高壓電(dian)(dian)(dian)路,選用瓷介電(dian)(dian)(dian)容和云母貫穿(chuan)電(dian)(dian)(dian)容;
  3、對于諧振(zhen)電(dian)路,宜用云母(mu)電(dian)容、陶(tao)瓷(ci)貫穿(chuan)電(dian)容和有機薄膜貫穿(chuan)電(dian)容;
4、對于隔直電路,建(jian)議選用滌綸電容(rong)、云母和陶瓷(ci)貫穿電容(rong);
5、對于諧振(zhen)回路可選(xuan)用(yong)空氣(qi)電容(rong)、云母(mu)電容(rong)、高(gao)頻陶瓷電容(rong)、小型密封可變(bian)貫穿電容(rong)等。
貫(guan)穿(chuan)電容組回路(lu)一般不(bu)裝設電流速斷(duan)保(bao)護(hu),因為速斷(duan)保(bao)護(hu)要考慮躲過貫(guan)穿(chuan)電容組合(he)閘沖擊電流及對外放電電流的影(ying)響,其保(bao)護(hu)范(fan)圍和(he)效果(guo)不(bu)能充(chong)分利用。
