GS4B034020GGT

GS4B034020GGT Description

The GS4B034020GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision applications. It features a 402Ω resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched-resistor circuits. The thin-film technology delivers a low ±25ppm/°C temperature coefficient, making it ideal for environments with thermal fluctuations. Rated for 0.05W (1/20) per resistor and 0.4W total power dissipation, it operates reliably across a 70°C to 125°C derated temperature range, with a maximum operating temperature of 125°C. The 100V maximum voltage rating and surface-mount gull-wing termination suit high-density PCB designs.
