GS4B034220DCT

GS4B034220DCT Description

The GS4B034220DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 422 Ω resistance value per element with a tight 0.5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in an 8-pin SOIC ceramic package, it offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while the tube packaging ensures safe handling and storage.
