摘　　要：该篇文章先介绍了现有的105℃2000小时系列450V焊片式铝电解电容器的设计及试验失效的现象。并通过对105℃2000小时系列的设计与现有的105℃3000小时系列的设计进行对比,分析了105℃2000小时450V高电压电容器在设计上的一些不足之处。接着对这些不足之处进行了改进的设计,并将改进了的设计规则应用在220μF/390μF/680μF/820μF这四种不同容量的产品上,将其做成产品。最后对产品进行纹波寿命,直流寿命等试验并分析了结果。This paper introduces the existing design of 105℃2000-hours series 450V snap-in aluminum electrolytic capacitor and the failure of the test.By comparing the design of 105℃2000-hours series with that of existing 105℃3000-hours series,it analyzes design defects of 105℃2000-hours 450V high voltage capacitor.Then,this paper overcomes the defects,improves the design,and applies the improved design rules to products of four different capacities 220μF,390μF,680μF and 820μF and make products out of them.Finally,this paper tests the product's ripple lifespan and DC lifespan and analyzes the results.
