GS4A031913FT Description

The GS4A031913FT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for demanding isolation and signal conditioning applications. Built with thin-film technology on a ceramic substrate, it delivers exceptional stability with a ±25ppm/°C temperature coefficient and ±1% tolerance across its 191kΩ resistance value per element. The isolated circuit design (ISOL) ensures independent resistor performance, while the SOIC-C series construction provides robust mechanical and thermal reliability. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it operates over a wide temperature range (-70°C to +125°C), making it suitable for harsh environments. The gull-wing termination and 1.27mm pitch enable easy surface-mount assembly.
