高频低阻抗片式固体电解电容器的进展

Advance of chip solid electrolytic capacitors of high frequency and low impedance

为降低片式固体电解电容器的等效串联电阻从而改善电容器阻抗－频率特性，国外采用了导电功能高分子材料聚吡咯作电解质，代替原用的ＭｎＯ２、有机半导体ＴＣＮＱ取得显著效果，国内已开展了导电聚吡咯的应用研究。

To reduce ESR and therefore improve impedance characteristic, polypyrrole has been used to take the place of MnO 2 and TCNQ as electrolytic by some overseas manufacturers. A good result has been achieved. In China, the application of ploypyrrole is under development.(11 refs )
