GUS-QS0B-03-7500-CA Description

The GUS-QS0B-03-7500-CA 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 750Ω resistance value and an ultra-tight 0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance 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 reliability in compact designs. Packaged in a tube for automated assembly, this non-automotive, non-PPAP compliant component is ideal for industrial and instrumentation use.
