GS4B034220FBT Description

The GS4B034220FBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. With a 422Ω resistance per element and tight 1% tolerance, it delivers stable performance in demanding circuits. The ceramic-based construction ensures excellent thermal stability, operating from 70°C to 125°C with a derated power profile. Its ±25ppm/°C temperature coefficient minimizes resistance drift, while the 0.4W total power rating (0.05W per resistor) suits low-power designs. The gull-wing termination and 1.27mm pitch enable reliable PCB integration.
