GUS-QS0B-02-3901-BB Description

The GUS-QS0B-02-3901-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 3.9KΩ 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, with a derated power rating of 0.05W (1/20W) per resistor and a total power dissipation of 1W. Its ±50ppm/°C temperature coefficient guarantees stable performance in thermally dynamic environments. The gull-wing termination and surface-mount design facilitate reliable PCB assembly, while the 100V maximum voltage rating makes it suitable for both low and moderate voltage circuits.
