GUS-QS0B-03-4641-D Description

The GUS-QS0B-03-4641-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors with a 4.64KΩ resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with automated PCB assembly processes. The non-automotive and non-PPAP compliant device is supplied in a tube packaging, making it suitable for prototyping and volume production.
