GUS-QS8B-02-4022-J Description

The GUS-QS8B-02-4022-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 40.2KΩ resistance value and a 5% tolerance, delivering a total power rating of 0.75W (3/4W). Its thin-film technology ensures excellent stability, with a low temperature coefficient of ±50ppm/°C, making it ideal for environments with operating temperatures ranging from 70°C to 125°C. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the compact dimensions (4.9mm x 6.02mm x 1.47mm) save board space.

GUS-QS8B-02-4022-J Features

• High Precision: Thin-film construction ensures low TCR (±50ppm/°C) and stable performance under thermal stress.
• Robust Power Handling: 0.05W per resistor (total 0.75W) with a maximum voltage rating of 100V.
• Compact & Durable: QSOP package with 16 gull-wing terminals (0.64mm pitch) for reliable SMT assembly.
• Wide Temperature Range: Operates reliably from -55°C to +125°C, derated for 70°C to 125°C at full power.
• Automotive & Industrial Suitability: Though not PPAP or automotive-rated, its high reliability suits industrial controls, test equipment, and telecom systems.

GUS-QS8B-02-4022-J Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance (5%).
• Signal Conditioning: Ideal for ADC/DAC reference networks due to low TCR and minimal drift.
• Embedded Systems: Space-constrained designs in medical devices, instrumentation, and communication hardware.
• Power Management: Distributed resistor networks in DC-DC converters or load-sharing applications.
