GUS-QS8A-02-4751-JB Description

The GUS-QS8A-02-4751-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated resistors, each with a 4.75KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal thermal performance. The device features a ±50ppm/°C temperature coefficient, minimizing resistance drift in fluctuating environments. Its gull-wing termination and 0.64mm terminal pitch facilitate robust soldering and high-density layouts.

GUS-QS8A-02-4751-JB Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Thin-Film Technology: Delivers superior stability, low noise, and tight TCR (±50ppm/°C) for precision circuits.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports demanding applications.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint ideal for space-constrained designs.
• Wide Voltage Rating: 100V maximum ensures compatibility with industrial and telecom voltages.
• Non-Automotive Grade: Suitable for commercial and industrial use (PPAP not required).

GUS-QS8A-02-4751-JB Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces and ADC/DAC circuits.
• Industrial Controls: Isolated feedback networks in PLCs and motor drives.
• Telecom Equipment: Impedance matching and termination in high-frequency modules.
