GUS-QS8A-02-7871-JB Description

The GUS-QS8A-02-7871-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 features 8 isolated resistors, each with a 7.87KΩ 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 ±50ppm/°C temperature coefficient guarantees stability in fluctuating environments, while the 100V maximum voltage rating enhances durability in high-voltage circuits.

GUS-QS8A-02-7871-JB Features

• Isolated Resistor Network: 8 independent resistors (ISOL circuit designator) for flexible circuit design.
• Thin-Film Technology: Delivers low noise, high accuracy (±50ppm/°C), and long-term reliability.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with gull-wing terminals (0.64mm pitch) for secure SMD mounting.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) suits compact, power-sensitive designs.
• Wide Operating Range: Stable performance from -55°C to 125°C (derated above 70°C).
• Non-Automotive Grade: Ideal for industrial and consumer electronics where PPAP compliance is unnecessary.
