GUS-QS0B-03-1431-JA Description

The GUS-QS0B-03-1431-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors with a uniform 1.43KΩ resistance value, offering a 5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design ensure compatibility with automated PCB assembly processes. The compact 8.66mm × 6.02mm × 1.47mm footprint and ±0.1mm dimensional tolerances make it ideal for space-constrained designs.

GUS-QS0B-03-1431-JA Features

• High-Density Integration: Combines 19 resistors in a single QSOP-20 package, reducing board space and assembly complexity.
• Stable Thin-Film Technology: Delivers low noise, high accuracy (±5%), and excellent thermal stability (±25ppm/°C).
• Robust Power Handling: 1W total power rating with derated performance up to 125°C, suitable for demanding environments.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch enable seamless SMT placement.
• Wide Voltage Range: Supports applications up to 100V, making it versatile for analog and digital circuits.
• Non-Automotive/Non-PPAP: Optimized for industrial, telecom, and instrumentation use (not automotive-qualified).
