GUS-QS0B-02-1021-CA Description

The GUS-QS0B-02-1021-CA 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 with a 1.02KΩ resistance value, offering a tight tolerance of ±0.25% and a low temperature coefficient of ±50ppm/°C. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and surface-mount design ensure easy PCB integration, while the 100V maximum voltage rating enhances versatility in high-voltage circuits.
