家用电器的制作和维修经常会用到晶体三极管。选用三极管首先要了解它的放大倍数。而日本产三极管在我国使用最为普遍。怎样从它的管型标记知道其确切的放大倍数H_(EE)((?))(共发射极静态电流放大系数)范围,这是人们所关心的,而这方面资料又不多见。笔者根据个人实践,积累了一些数据,现列出日产有关品牌的晶体管及其对应的H_(EE)标记所指的放大倍数,具体见下表所示。
The manufacture and maintenance of household appliances often use transistors. Select the transistor must first understand it’s magnification. The production of transistor in Japan is the most common use. It is a matter of concern that how to know the exact magnification H_ (EE) ((?)) (Common emitter quiescent current amplification factor) range from its tube type markings is very rare. The author has accumulated some data according to personal practice and now lists the magnification indicated by the Nissan brand of transistor and its corresponding H EE mark, as shown in the following table.
