GUS-QS8B-02-5490-GF Description

The GUS-QS8B-02-5490-GF 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 integrates 15 resistors, each with a 549Ω resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, making it suitable for demanding environments. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its robustness. Packaged in a tube for secure handling, this surface-mount component features gull-wing terminals for easy PCB integration.

GUS-QS8B-02-5490-GF Features

• Precision Thin Film Technology: Ensures low noise and high stability.
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
