GS4B033400GT

GS4B033400GT Description

The GS4B033400GT 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 340Ω resistance value with a tight ±2% absolute tolerance and an ultra-stable ±25ppm/°C temperature coefficient. The thin-film technology ensures low noise and high reliability, while the ceramic case style enhances 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, with a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly.
