GS4B034220GGT

GS4B034220GGT Description

The GS4B034220GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 7-resistor bussed network features a 422Ω resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in demanding circuits. 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 reliable surface-mount assembly. The thin-film technology delivers excellent stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 0.05W per resistor (0.4W total) and 100V maximum voltage, it operates reliably up to 125°C, with derated performance up to 70–125°C.
