GUS-QS8A-02-5621-JA Description

The GUS-QS8A-02-5621-JA 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 5.62KΩ resistance (5% tolerance) and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it delivers robust reliability in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density layouts. Packaged in a tube, this RoHS-non-compliant component is ideal for industrial and commercial electronics requiring isolated resistor networks.

GUS-QS8A-02-5621-JA Features

• Precision Thin Film Technology: Offers low noise and high stability (±50ppm/°C) for sensitive circuits.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C, superior to standard arrays.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint saves board space.
• Isolated Circuit Design (ISOL): Each resistor is electrically independent, enabling flexible circuit configurations.
• Automotive-Grade Alternatives: While not PPAP/Automotive certified, its 125°C operating range suits harsh environments.
• Gull-Wing SMT Termination: Ensures reliable solder joints in automated assembly processes.

GUS-QS8A-02-5621-JA Applications

• Signal Conditioning: Isolated resistor networks for ADC/DAC reference dividers.
• Industrial Controls: Precision voltage dividers in PLCs and sensor interfaces.
• Test & Measurement Equipment: Stable resistance paths in calibration circuits.
• Medical Electronics: Low-drift networks for diagnostic devices (non-RoHS compliant).
• Power Management: Feedback networks in DC-DC converters, leveraging high voltage tolerance.

Conclusion of GUS-QS8A-02-5621-JA

The GUS-QS8A-02-5621-JA excels in space-constrained, high-reliability applications demanding precision and thermal stability. Its thin-film isolation, robust power rating, and compact QSOP package make it a standout choice over bulkier or less stable alternatives. While unsuitable for automotive or RoHS-regulated designs, it is a cost-effective solution for industrial, medical, and instrumentation systems requiring repeatable performance under thermal stress.
