GUS-QS0B-03-4121-JD Description

The GUS-QS0B-03-4121-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 4.12KΩ resistance value and a 5% tolerance, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability under thermal stress. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in high-density layouts.

GUS-QS0B-03-4121-JD Features

• Thin-Film Technology: Offers superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
