SILICON TRANSISTOR
2SC3841
UHF OSCILLATOR AND UHF MIXER
NPN SILICON EPITAXIAL TRANSISTOR
MINI MOLD
DESCRIPTION
The 2SC3841 is an NPN silicon epitaxial transistor intended for use as
UHF oscillators and a UHF mixer in a tuner of a TV receiver.
The device features stable oscillation and small frequency drift against
any change of the supply voltage and the ambient temperature.
It is designed for use in small type equipments especially recommendd
for Hybried Integrated Circuit and other applications.
