GS4B034422FCT Description

The GS4B034422FCT 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 44.2KΩ resistance value, 1% tolerance, and ±25ppm/°C temperature coefficient, this component ensures stable performance in demanding environments. Its ceramic case style and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) supports efficient power dissipation. Rated for 100V maximum voltage and operating within 70°C to 125°C, it is ideal for precision analog and digital circuits requiring tight tolerance and low drift.
