GUS-QS0B-03-2102-GC Description

The GUS-QS0B-03-2102-GC 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 21KΩ resistance value and a tight 2% tolerance, ensuring consistent performance across all channels. 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 high-reliability designs. Packaged in a tube for automated assembly, this surface-mount (SMD) component features gull-wing terminals with a 0.64mm pitch, enabling compact PCB layouts.

GUS-QS0B-03-2102-GC Features
