BC108

BC107 BC108 LOW NOISE GENERAL PURPOSE AUDIO AMPLIFIERS DESCRIPTION The BC107 and BC108 are silicon planar epitaxial NPN transistors in TO-18 metal case. They are suitable for use in driver stages, low noise input stages and signal processing circuits of television reveivers. The PNP complemet for BC107 is BC177.
