GUS-QS8A-02-6490-JB Description

The GUS-QS8A-02-6490-JB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing surface-mount termination, this 649Ω ±5% resistor array delivers 0.75W (3/4W) total power dissipation and operates across a wide temperature range of 70°C to 125°C. Its thin film technology ensures low noise and stable performance, with a ±50ppm/°C temperature coefficient, making it ideal for environments requiring tight tolerance and reliability. The isolated (ISOL) circuit design allows independent resistor functionality, while the 100V maximum voltage rating enhances versatility in high-voltage circuits.

GUS-QS8A-02-6490-JB Features

• Precision Thin Film Technology: Offers superior stability and low noise compared to thick film alternatives.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• High Power Handling: 0.1W per resistor (0.75W total) with derated performance up to 125°C.
• Isolated Resistor Configuration: Each of the 8 resistors operates independently, enabling flexible circuit design.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its robust construction suits industrial and telecom applications.
• Non-RoHS Compliant: Suitable for legacy or niche applications where RoHS exemptions apply.
