GUS-QS0B-03-2940-CC Description

The GUS-QS0B-03-2940-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 294Ω resistance value, 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 harsh environments. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes board space.
