GUS-QS8A-03-2740-FB Description

The GUS-QS8A-03-2740-FB 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 274Ω resistance value and a tight 1% tolerance. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it ensures reliable operation in demanding environments. The ±25ppm/°C temperature coefficient guarantees stability across a wide operating range of -55°C to +125°C, making it suitable for high-accuracy circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the compact dimensions (4.9mm x 6.02mm x 1.47mm) save PCB space.

GUS-QS8A-03-2740-FB Features

• High Precision: Thin-film technology ensures low TCR (±25ppm/°C) and 1% tolerance for stable performance.
• Robust Construction: QSOP package with isolated resistors (ISOL) minimizes crosstalk and thermal interference.
• Power Efficiency: 0.75W total power dissipation (0.1W per resistor) supports high-density designs.
