GUS-QS0B-03-1003-BA Description

The GUS-QS0B-03-1003-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 100K Ohm resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. 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 low ±25ppm/°C temperature coefficient for stable performance under thermal stress. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while the compact 8.66mm × 6.02mm × 1.47mm footprint saves board space.
