DESCRIPTION
The NE686 series of NPN epitaxial silicon transistors are
designed for low voltage/low current, amplifier and oscillator
applications. NE686's high f
T
make it an excellent choice for
portable wireless applications up to 5 GHz. The NE686 die is
available in six different low cost plastic surface mount pack-
age styles.
