GS4A034221GGT Description

The GS4A034221GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 4.22KΩ and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its ±25ppm/°C temperature coefficient guarantees stable performance under thermal stress. The SOIC-C series construction offers superior mechanical robustness, with a rectangular ceramic case and gull-wing termination for secure surface mounting.
