GUS-QS0B-03-1872-JB Description

The GUS-QS0B-03-1872-JB 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 with a uniform 18.7KΩ resistance value, offering a 5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained layouts. Packaged in a protective tube, this non-automotive, non-PPAP compliant component is RoHS non-compliant but excels in industrial and commercial electronics.
