DESCRIPTION
The 2SC4228 is a low supply voltage transistor designed for VHF,
UHF low noise amplifier.
It is suitable for a high density surface mount assembly since the
transistor has been applied super mini mold package.
This is achieved by direct nitride passivated base surface process
(NESAT
TM
process) which is an NEC proprietary fabrication technique.
