GUS-QS0B-03-6491-J Description

The GUS-QS0B-03-6491-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding environments. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 6.49KΩ resistance value and a tight 5% tolerance, ensuring consistent performance across circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability over a wide operating 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 power-sensitive designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GUS-QS0B-03-6491-J Features
