GUS-QS0B-02-8251-DB Description

The GUS-QS0B-02-8251-DB 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 with a 8.25KΩ resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C. With a 1W total power rating (0.05W per resistor) and a maximum operating temperature of 125°C, it ensures reliable performance in thermally challenging environments. The gull-wing termination and QSOP package (8.66mm x 6.02mm x 1.47mm) facilitate compact PCB designs while maintaining mechanical stability.
