T ^{h e f o l l o wdi nagt a s h e e t a r ed e s i g n . NEC's NE680 series of NPN epitaxial silicon transistors is}
designed for low noise, high gain and low cost applications.
t ^{h i s f o r n e w Both the chip and micro-x versions are suitable for applications}
f ^{o r up to 6 GHz. The NE680 die is also available in six different low}
f ^{r o m e n d e d o f f i c e cost plastic surface mount package styles. The NE680's high}
fT makes it ideal for low voltage/low current applications, down
to as low as 0.5 V / 0.5 mA. IC max for the NE680 series is
r ^{e c o m m c a l l s a l e s 35 mA. For higher current applications see the NE681 series.}
