GUS-QS8A-02-1541-CB Description

The GUS-QS8A-02-1541-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.54 kΩ resistance value and an ultra-tight ±0.25% tolerance. The device 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 thermally challenging environments. With a ±50 ppm/°C temperature coefficient, it ensures stable performance under varying thermal conditions. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating provide robust electrical characteristics for precision circuits.
