GUS-QS0B-03-3922-FA Description

The GUS-QS0B-03-3922-FA 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 39.2KΩ resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) and can withstand a maximum operating temperature of 125°C, making it suitable for environments with thermal stress. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability under varying thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in high-performance designs.
