DESCRIPTION
PACKAGE DIMENSIONS
The 2SC4228 is a low supply voltage transistor designed for VHF,
UHF low noise amplifier.
in millimeters
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
(NESATTM process) which is an NEC proprietary fabrication technique.
