GUS-QS8A-03-7501-JB Description

The GUS-QS8A-03-7501-JB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin QSOP package with gull-wing terminations, this 7.5KΩ isolated resistor array offers a 5% tolerance and a low ±25ppm/°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 0.1W per resistor, it supports robust operation in compact, surface-mount designs. The 100V maximum voltage rating and thin-film technology provide excellent reliability for signal conditioning, voltage division, and impedance matching in demanding environments.

GUS-QS8A-03-7501-JB Features

• Precision Thin Film: Delivers superior accuracy (±25ppm/°C) and stability for critical circuits.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) in a compact 4.9mm x 6.02mm x 1.47mm footprint.
• Isolated Design (ISOL): Each resistor operates independently, ideal for multi-channel isolation.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated power up to 125°C).
• QSOP Package: 16-pin gull-wing SMD with 0.64mm pitch for high-density PCB layouts.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications.

GUS-QS8A-03-7501-JB Applications
