GUS-QS0B-03-9760-C Description

The GUS-QS0B-03-9760-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 976Ω resistance value and an exceptional ±0.25% tolerance, ensuring consistent performance in precision circuits. With a ±25ppm/°C temperature coefficient, it maintains stability across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust performance in compact designs. Its gull-wing termination ensures reliable solder joints for automated PCB assembly.
