BC846 THRU BC849
NPN Silicon Epitaxial Planar Transistors
for switching and AF amplifier applications.
Especially suited for automatic insertion in
thick- and thin-film circuits.
These transistors are subdivided into three
groups A, B and C according to their current gain. The
type BC846 is available in groups A and B, however, the
types BC847 and BC848 can be supplied in all three
groups. The BC849 is a low noise type available in groups
B and C. As complementary types, the PNP transistors
BC856...BC859 are recommended.
