GUS-QS0B-03-7501-BB Description

The GUS-QS0B-03-7501-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 7.5K Ohm resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. The network operates over a wide temperature range of 70°C to 125°C (derated) and can withstand 125°C maximum operating temperature, making it suitable for harsh environments. With a ±25ppm/°C temperature coefficient, it delivers stable performance under thermal stress. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in precision circuits.
