DATA SHEET
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.
