FEATURES
DESCRIPTION
The NE680M03 transistor is designed for low noise, high gain,
and low cost applications. This high f
voltage/low current applications. NEC's new low profile/flat
lead style "M03" package is ideal for today's portable wireless
applications. The NE680 is also available in chip, Micro-x, and
six different low cost plastic surface mount package styles.
