GUS-QS8A-02-3902-GG Description

The GUS-QS8A-02-3902-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 39KΩ resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) save PCB space.

GUS-QS8A-02-3902-GG Features

• Isolated Resistor Network: 8 independent 39KΩ resistors with 100V maximum voltage rating, ideal for signal isolation.
• Precision Thin-Film Technology: Delivers low noise, high stability, and tight tolerance (±2%) for critical circuits.
