DESCRIPTION
NEC's NE687M03 transistor is designed for low noise, high
gain, and low cost requirements. This high f
T
part is well suited
for very low voltage/low current designs for portable wireless
communications and cellular radio applications. NEC's new
low profile/flat lead style "M03" package is ideal for today's
portable wireless applications. The NE687 is also available in
six different low cost plastic surface mount package styles.
