GUS-QS8A-02-6491-JB Description

The GUS-QS8A-02-6491-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 6.49KΩ resistance value with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package, it offers a compact 4.9mm × 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust handling of moderate power loads.

GUS-QS8A-02-6491-JB Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent stability.
• Isolated Resistors (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• High Voltage Rating (100V): Suitable for industrial and instrumentation applications.
• Wide Operating Range: Performs reliably from -55°C to +125°C (derated power up to 125°C).
• QSOP Package: Compact 16-pin design with 0.64mm terminal pitch for high-density PCB layouts.
• Non-Automotive Grade: Optimized for general-purpose and industrial use (PPAP not required).

GUS-QS8A-02-6491-JB Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces.
• Signal Conditioning: Isolation and impedance matching in data acquisition systems.
• Medical Electronics: Patient monitoring equipment where stability and accuracy are critical.
• Test & Measurement: Calibration circuits and reference networks.
