一、引言铝电解电容器自问世以来,随着电子科学技术的飞跃发展,它在电子科学技术中应用很广,数量较大,品种繁多,这是人所共知的。它是电子科学技术发展不可缺少的非常重要的元件之一。小型铝电解电容器一般指小容量(几百微法以内)低耐压(几十伏以内)的铝电解电容器,它在电路中有以下几种用途:1) I. Introduction Since the advent of aluminum electrolytic capacitors, with the rapid development of electronic science and technology, it is widely used in electronic science and technology, a large number, a wide variety, it is well known. It is one of the most important components necessary for the development of electronic science and technology. Small aluminum electrolytic capacitors generally refers to the small capacity (within a few hundred micro-law) low voltage (dozens of volts less) aluminum electrolytic capacitors, which has the following uses in the circuit: 1)
