GUS-QS8A-03-8250-GA Description

The GUS-QS8A-03-8250-GA 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 SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. Each resistor features an 825Ω ±2% tolerance, ±25ppm/°C temperature coefficient, and 0.1W (1/10W) power rating per element, with a total power dissipation of 0.75W (3/4W). The isolated (ISOL) circuit design ensures independent resistor operation, while the 100V maximum voltage rating and 125°C operating temperature range suit demanding environments.

GUS-QS8A-03-8250-GA Features

• Thin Film Technology: Delivers superior stability, low noise, and tight tolerance (±2%) for precision circuits.
• High Power Density: 0.75W total power in a miniature QSOP package, outperforming similar networks in thermal management.
• Wide Temperature Range: Operates from 70°C to 125°C @ derated power, ensuring reliability in industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Robust Construction: Gull wing termination and ±0.1mm height/length tolerances enhance mechanical durability for surface mounting.
• Non-RoHS Compliance: Suitable for legacy or niche applications requiring non-compliant materials.
