貼片鋁質電解電容與(yu)傳統(tong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)相比，它采用(yong)(yong)具有(you)高導(dao)電(dian)(dian)(dian)(dian)(dian)度(du)、高穩定性(xing)的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)高分子材料作為固態電(dian)(dian)(dian)(dian)(dian)解(jie)(jie)質(zhi)，代替了傳統(tong)鋁質(zhi)電(dian)(dian)(dian)(dian)(dian)解(jie)(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液，它所(suo)采用(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)(jie)質(zhi)電(dian)(dian)(dian)(dian)(dian)導(dao)率很(hen)高，再加上其獨特(te)的(de)(de)(de)結構設計，大(da)幅度(du)改(gai)善傳統(tong)液態鋁電(dian)(dian)(dian)(dian)(dian)解(jie)(jie)電(dian)(dian)(dian)(dian)(dian)容(rong)器的(de)(de)(de)缺點，展現出(chu)極為優(you)異的(de)(de)(de)特(te)性(xing)。

1、鋁質電解電容理想的高頻低阻抗特性。高分子聚合物固體電解電容器的損耗極低，具有理想的高頻低阻抗特性，所以廣泛應用于退藕、濾波設計等電路中，效果理想，特別是高頻濾波效果優秀。通過一個實驗可以更加直觀和清除地看出高分子聚合物固體鋁電解電容器與普通電容器之間的高頻特性明顯差異。在平滑電路輸入疊加1MHz(峰一封值電壓8V)高頻干擾信號，用1只47UF的高分子聚合物固體電解電容器濾波，可使噪聲降到僅有峰一峰電壓30mv輸出。要達到同樣的濾波效果，需要并聯4只1000UF的普通型液態鋁電解電容器，或者并聯接入3只100UF的鉭電解電容器。

2、鋁質電解電容耐大紋波電流能力強。高分子聚合物固體電解電容器具有耐大紋波電流的能力，適宜在開關電源電路中短時間內提供較大的電流。短時間內端電壓下降明顯，所以對外提供高頻電流的能力很強，具備很好的瞬間響應特性。

3、鋁質電解電容頻率(lv)特性(xing)(xing)(xing)平坦和(he)溫度(du)特性(xing)(xing)(xing)良(liang)好。高(gao)(gao)(gao)分(fen)子聚(ju)合物固(gu)體電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)在(zai)0、1~10MHz頻段內具(ju)(ju)有平坦的電(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)——頻率(lv)特性(xing)(xing)(xing)。它還具(ju)(ju)有極佳的溫度(du)特性(xing)(xing)(xing)，一般(ban)溫度(du)從(cong)-55度(du)變到(dao)105度(du)，電(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)僅改(gai)變-5%~+8%高(gao)(gao)(gao)分(fen)子聚(ju)合物固(gu)體鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)還具(ju)(ju)有長(chang)壽命(ming)、高(gao)(gao)(gao)可靠性(xing)(xing)(xing)、它主要應用于(yu)主板旁路(lu)(lu)電(dian)(dian)(dian)(dian)容(rong)(rong)、DC/DC變換(huan)器(qi)、小型大功(gong)率(lv)電(dian)(dian)(dian)(dian)源(yuan)、電(dian)(dian)(dian)(dian)源(yuan)退藕、高(gao)(gao)(gao)頻噪聲(sheng)抑(yi)制電(dian)(dian)(dian)(dian)路(lu)(lu)及便攜(xie)式(shi)電(dian)(dian)(dian)(dian)子設備等。高(gao)(gao)(gao)分(fen)子聚(ju)合物固(gu)體鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)由于(yu)使(shi)用鋁和(he)導電(dian)(dian)(dian)(dian)高(gao)(gao)(gao)分(fen)子聚(ju)合物材(cai)料(liao)，因此不會燃(ran)燒或冒煙，不會爆(bao)炸。
