Nov 21, 2011 · Per @mgburr and Lancelot: A 2N3904 transistor’s beta max value is 150 and min value is 100. When figuring out DC current gain, the beta value is part of the formula. In the sheet above, it is also known as as hFE. (hFE = beta = gain for easier understanding) So if you need to build an amplifier with a gain of 300, you set up 3 transistor stages.
