GS4B039312FBT Description

The GS4B039312FBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC gull-wing SMD package, designed for surface-mount applications. With a 93.1kΩ resistance per resistor and a tight 1% tolerance, this network ensures reliable signal conditioning and voltage division in compact PCB designs. The ceramic case enhances thermal stability, while the thin film technology provides excellent ±25ppm/°C temperature coefficient for minimal drift across the -70°C to +125°C operating range. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it suits moderate-power applications requiring precision and durability.
