GS4B031271FFT

GS4B031271FFT Description

The GS4B031271FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features a 1.27KΩ resistance value with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in precision circuits. The thin-film technology delivers excellent stability with a low ±25ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 0.05W (1/20) per resistor and 0.4W total power dissipation, it operates reliably within a -55°C to +125°C range, derating up to 125°C. Its 100V maximum voltage rating and surface-mount gull-wing termination enhance its versatility in compact PCB designs.
