GUS-QS0B-03-4321-CC Description

The GUS-QS0B-03-4321-CC 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 with a 4.32KΩ resistance value per element, offering a tight tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C. With a 1W total power rating (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, making it suitable for environments requiring stability under thermal stress. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the compact 8.66mm × 6.02mm × 1.47mm footprint maximizes board space efficiency.
