GUS-QS0B-03-8251-JA Description

The GUS-QS0B-03-8251-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a resistance value of 8.25KΩ and a 5% tolerance, delivering a total power rating of 1W. The network operates over a wide temperature range of -55°C to +125°C, with derated power performance from 70°C to 125°C. Its ±25ppm/°C temperature coefficient ensures stability in thermally demanding environments, while the 100V maximum voltage rating and gull-wing termination enhance reliability in compact PCB designs.

GUS-QS0B-03-8251-JA Features
