2SC4228 - NPN Transistor

General 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.

DATA SHEET SILICON TRANSISTOR 2SC4228 HIGH FREQUENCY LOW NOISE AMPLIFIER NPN SILICON EPITAXIAL TRANSISTOR SUPER MINI MOLD 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 (NESATTM process) which is an NEC proprietary fabrication technique.
