GUS-QS0B-02-2552-BB Description

The GUS-QS0B-02-2552-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 25.5KΩ resistance value 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 withstands a maximum operating temperature of 125°C, making it suitable for harsh environments. With a ±50ppm/°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.
