BC107
BC107B
Low noise general purpose audio amplifiers



Description
The BC107 and BC107B 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 receivers. The PNP complementary
types are BC177 and BC177B respectively.
