GS4B021021FAT Description

The GS4B021021FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 1.02KΩ resistance value with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, it provides excellent thermal stability and mechanical durability. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.
