GS4B033740JT

GS4B033740JT Description

The GS4B033740JT 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 374Ω resistance value with a ±5% absolute tolerance and an ultra-stable ±25ppm/°C temperature coefficient. The thin-film technology ensures low noise and high reliability, while the ceramic case provides excellent thermal stability. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly (SMT).
