NSF2250WT1
NPN Silicon Oscillator and
Mixer Transistor
The NSF2250WT1 NPN silicon epitaxial bipolar transistor is
intended for use in general purpose UHF oscillator and mixer
applications. It is suitable for automotive keyless entry and TV tuner
designs.
The device features stable oscillation and small frequency drift
during changes in the supply voltage and over the ambient temperature
range.
