SILICON TRANSISTOR

2SC4186

DESCRIPTION

The 2SC4186 is an NPN silicon epitaxial transistor intended for use

as a UHF oscillator and a 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 recom-

mended for Hybrid Integrated Circuit and other applications.
