NPN BC107 – BC108 – BC109
LOW NOISE GENERAL PURPOSE AUDIO AMPLIFIERS
The BC107, BC108 and BC109 are silicon planar epitaxial NPN transistors mounted in TO-18
metal package.
They are suitable for use in drive audio stages, low-noise input audio stages and as low power,
high gain general purpose transistors.
The complementary PNP are BC177, BC178 and BC179.
Compliance to RoHS.
