2SC4228 Datasheet (NEC) - NPN Transistor

2SC4228, NPN Transistor

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 (NESATTM process) which
