GUS-QS0B-03-6811-JB Description

The GUS-QS0B-03-6811-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 6.81KΩ resistance value and a tight 5% tolerance, ensuring consistent performance across industrial and commercial environments. 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. Packaged in a tube for secure handling, this surface-mount (SMD) component features gull-wing terminations for reliable PCB connections.
