GS4B034220JGT Description

The GS4B034220JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 7-resistor bussed network features a 422Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±2%, ensuring reliable signal integrity. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for surface-mount assembly. The thin-film technology delivers a low temperature coefficient of ±25ppm/°C, stable across a wide operating range of -70°C to +125°C. With a maximum voltage rating of 100V and a total power rating of 0.4W (0.05W per resistor), it balances power dissipation and space efficiency.
