GUS-QS0B-03-4301-JF Description

The GUS-QS0B-03-4301-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 4.3K Ohm resistance, 5% tolerance, and a ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The compact 8.66mm x 6.02mm x 1.47mm footprint and gull-wing termination ensure easy PCB integration, while its tube packaging protects during handling and assembly.
