GUS-QS8B-01-3741-B Description

The GUS-QS8B-01-3741-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 3.74KΩ resistance value, offering a tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient. With a 0.75W (3/4W) 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 precision analog and digital circuits. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.

GUS-QS8B-01-3741-B Features

• Precision Performance: 0.1% tolerance and ±100ppm/°C TCR ensure stability in critical applications.
• Robust Construction: Thin-film technology delivers low noise and high reliability.
• High Power Handling: 0.75W total power (0.05W per resistor) with derating up to 125°C.
