DESCRIPTION

The 2SC3545 is an NPN silicon epitaxial transistor intended for use as

UHF oscillator and 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

recommended for Hybrid Integrated Circuit and other applications.
