Transistor
2SC5474 (Tentative)
Silicon NPN epitaxial planer type
For low-voltage low-noise high-frequency oscillation
s ^Features
q High transition frequency f_T.
q High gain of 8.9dB and low noise of 1.8dB at 3V.
q Optimum for RF amplification of a portable telephone and
pager.
q SS-Mini type package, allowing downsizing of the equipment
and automatic insertion through the tape packing.
