GS4B011271CCT

GS4B011271CCT Description

The GS4B011271CCT 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 1.27KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating range of -70°C to +125°C. Housed in a ceramic SOIC-8 package, it features gull-wing SMD terminations for reliable surface-mount assembly. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits where space efficiency and signal integrity are critical.

GS4B011271CCT Features
