DESCRIPTION
NEC's NE681M03 transistor is ideal for low noise, high gain,
and low cost amplifier applications. NEC's new low profile/
flat lead style "M03" package is ideal for today's portable
wireless applications. The NE681 is also available in chip,
Micro-x, and six different low cost plastic surface mount
package styles.
