摘　　要：高压有机固体电解质片式钽电容器的高温特性是限制此类电容器广泛应用的瓶颈,目前国际上普遍采用105℃的温度上限,而不能满足125℃环境下的特殊使用要求。该文通过对电介质进行"屏蔽"和预处理,对有机固体电解质进行后处理和包封层改善,高压有机电解质片式钽电容器的高温特性得到明显改善,能够安全通过105℃、2 000 h和125℃、2 000 h寿命试验。该研究结果将为有机固体电解质片式钽电容器在特殊环境下的应用提供必要的技术支撑。The high temperature characteristics of high voltage organic chip tantalum capacitors are the bottlenecks to limit the wide applications of capacitors.At present,the temperature limit of 105℃is widely used in the world,but cannot meet the special requirements of 125℃environment.By the“shielding”and pretreatment of the dielectrics,the post treatment of the organic solid electrolyte,and the improvement of encapsulation layer,the high temperature characteristics of high voltage organic chip tantalum capacitors are significantly improved,and therefore the life tests of 105℃,2 000 h and 125℃,2 000 h have passed safely.This study will provide a technical support for the applications of organic chip tantalum capacitors in the special environment.
