GS4A034022FBT Description

The GS4A034022FBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 40.2 kΩ and an absolute tolerance of ±1%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, ensuring reliability in demanding environments. Its ±25 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision analog circuits. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination facilitates easy surface-mount assembly.
