GS4B021870GFT Description

The GS4B021870GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 187Ω resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. The thin-film technology and ceramic case provide excellent stability, with a low ±50ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 0.05W (1/20W) per resistor and 0.4W total power, it operates reliably within a -70°C to +125°C range, with a 100V maximum voltage rating. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
