GUS-QS0B-03-1051-GD Description

The GUS-QS0B-03-1051-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 1.05KΩ resistance value and a tight 2% tolerance. The network operates within a wide temperature range of 70°C to 125°C (derated power) and can withstand 125°C maximum operating temperature, making it suitable for demanding environments. With a ±25ppm/°C temperature coefficient, it ensures stable performance under thermal variations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in circuit designs.

GUS-QS0B-03-1051-GD Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent stability compared to thick-film alternatives.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCB layouts.
• Gull Wing Termination: Ensures robust surface-mount compatibility and solder joint reliability.
• High Power Density: 1W total dissipation across the network, with 0.05W per resistor, optimizing thermal management.
• Automotive & Industrial Suitability: While not automotive-grade, its 125°C rating and thin-film construction make it suitable for industrial controls, test equipment, and communication systems.
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring non-compliant materials.
