GUS-QS0B-03-5621-JD Description

The GUS-QS0B-03-5621-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 5.62KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating 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 demanding environments. Packaged in a tube, this surface-mount (SMD) component features gull-wing terminals for secure PCB attachment.

GUS-QS0B-03-5621-JD Features
