GUS-QS0B-03-9762-FF Description

The GUS-QS0B-03-9762-FF 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 97.6KΩ resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in high-density PCB designs. Packaged in a tube for automated assembly, this network is ideal for industrial and instrumentation applications where space efficiency and accuracy are critical.
