Brief introduction to the transistorTransistor, the full name should be the semiconductor transistor, also known as bipolar transistor, crystal transistor, is a current control current of semiconductor devices and its role is to enlarge the weak signal to a large number of electric signal, also used as a non-contact switch. Crystal transistor, is one of the basic components of the semiconductor, with current amplification, is the core element of the electronic circuit.

How to do a good selection of componentsThe main method for the selection of components is: appearance inspection, temperature cycle, high temperature life, electric power, sealing test, electric parameter test, function test.
