GUS-QS0B-03-2740-J Description

The GUS-QS0B-03-2740-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor network features a 274Ω resistance value per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this non-automotive, EAR99/Non-RoHS compliant component is optimized for industrial and commercial electronics.

GUS-QS0B-03-2740-J Features

• High-Density Integration: 19 resistors in a QSOP-20 package reduce board space and simplify routing.
• Precision Thin-Film Technology: Delivers low TCR (±25ppm/°C) and tight tolerance (5%) for stable signal conditioning.
• Robust Power Handling: 1W total dissipation (0.05W per resistor) supports moderate-power applications.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Surface-Mount Design: Gull-wing terminations and 0.64mm pitch enable automated assembly.
• Non-Automotive Grade: Suited for industrial controls, test equipment, and telecom infrastructure.
