NEC's NPN SILICON TRANSISTOR NE851M03
FEATURES
• NEW MINIATURE M03 PACKAGE:
– Small transistor outline
– Low profile / 0.59 mm package height
– Flat lead style for better RF performance
• IDEAL FOR ≤ 3 GHz OSCILLATORS
• LOW 1/f NOISE
• LOW PUSHING FACTOR
DESCRIPTION
NEC's NE851M03 transistor is designed for oscillator appli-
cations up to 3 GHz. The NE851M03 features low voltage
operation, low phase noise, and high immunty to pushing ef-
fects. NEC's low profile/flat lead style "M03" package is ideal
for today's portable wireless applications.
