GUS-QS0B-03-4751-DC Description

The GUS-QS0B-03-4751-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 4.75KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a 70°C to 125°C derated power range, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in precision analog and digital systems.

GUS-QS0B-03-4751-DC Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for minimal drift in critical applications.
• Robust Construction: Thin-film technology ensures low noise and high stability.
• Compact Design: 8.66mm × 6.02mm × 1.47mm QSOP package with 0.64mm pitch gull-wing leads for space-constrained PCBs.
