GUS-QS0B-03-5112-FA Description

The GUS-QS0B-03-5112-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 51.1K Ohm resistance value per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. Packaged in a 20-pin QSOP with gull-wing terminations, it offers a compact footprint (8.66mm x 6.02mm x 1.47mm) and robust 1W total power dissipation (0.05W per resistor). Its 100V maximum voltage rating and thin-film technology make it ideal for precision analog and digital circuits.

GUS-QS0B-03-5112-FA Features
