GUS-QS0B-03-2102-DD Description

The GUS-QS0B-03-2102-DD 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 21K Ohm resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of 70°C to 125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GUS-QS0B-03-2102-DD Features
