GUS-QS8B-03-4992-J Description

The GUS-QS8B-03-4992-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 49.9K Ohm resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating temperature range of 70°C to 125°C. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GUS-QS8B-03-4992-J Features

• Precision Thin Film Technology: Ensures low noise and high accuracy (±25ppm/°C) for critical analog and digital circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained designs.
• Robust Power Handling: 0.75W total dissipation (0.05W per resistor) enables use in power-sensitive applications without derating concerns.
• Wide Temperature Range: Operates reliably from 70°C to 125°C, suitable for industrial and automotive environments (though not PPAP or Automotive-qualified).
• Gull-Wing SMD Termination: Enhances solder joint reliability and mechanical stability under thermal stress.
