Description
본 발명은 알루미늄 전해콘덴서의 고압용 전해액 조성물에 관한 것으로, 특히 충분한 내전압을 가지면서 전해액의 전도도가 향상되어 하이리플(high ripple)용 소형화 제품에 적용가능하며 고온에서 특성이 안정하여 사용온도 범위가 확대되고 장시간 사용 가능한 전해액 조성물에 관한 것이다.The present invention relates to an electrolytic solution composition for high pressure of an aluminum electrolytic capacitor, in particular, having a sufficient withstand voltage and improving the conductivity of the electrolytic solution, which is applicable to a miniaturized product for high ripple, and has a stable temperature at high temperature, and thus an operating temperature range. It relates to an electrolyte solution composition which is expanded and can be used for a long time.

Was used by dissolving.

There is a drawback that the case's explosion proof acts as a wave.
