Bipolar Transistors 2N3055/MJ2955 Selected Products with hfe Selected products with measurement reports, measured by the seller. Special products selected by measuring and choosing from a large number of transistors. The operation of the circuit can be ideal when the hfe of the transistors, both NPN and PNP, are close. Both NPN and PNP were measured by passing the same base current. Please refer to the diagram for the measurement method. Part 3 Measured values: 2N3055 hfe, 60 hfe, 66 MJ2955 hfe, 64 hfe, 66 This is the set. The measured values are written on the back of the transistors. These are the measured and paired transistors when I made a transistor amplifier, and I am selling the remaining ones. Please comment if you have any questions. Please only trade with those who understand the above. #Transistor #Stone #Power Amplifier #Complementary Pair #Electronic DIY
