GUS-QS0B-03-1003-JA Description

The GUS-QS0B-03-1003-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 19 resistors in a 20-pin QSOP package, each with a 100KΩ resistance value and a 5% tolerance. With a ±25ppm/°C temperature coefficient, this network ensures stable performance across a wide temperature range (70°C to 125°C). The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design (6.02mm x 8.66mm footprint, 1.47mm height) enable compact PCB integration.
