GUS-QS8A-02-3480-JA Description

The GUS-QS8A-02-3480-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated resistors, each with a 348Ω resistance value and a 5% tolerance, ensuring stable performance in demanding environments. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining accuracy. The device operates across a wide temperature range of -70°C to +125°C, with a low temperature coefficient of ±50ppm/°C, minimizing resistance drift under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated SMT processes.

GUS-QS8A-02-3480-JA Features

• Precision Thin Film Technology: Delivers superior stability, low noise, and tight tolerance (±5%) for signal conditioning and voltage division.
• High Power Handling: 0.75W total rating (0.1W per resistor) enables use in power-sensitive circuits without derating below 125°C.
• Isolated Resistor Network (ISOL): Each resistor is electrically independent, ideal for multi-channel isolation in analog/digital systems.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with a 1.63mm seated height ensures compact footprint and mechanical durability.
• Wide Voltage Range: Supports up to 100V maximum rating, suitable for industrial and instrumentation applications.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use where PPAP compliance is not required.

GUS-QS8A-02-3480-JA Applications

• Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Medical Electronics: Patient monitoring systems requiring stable resistance under thermal cycling.
• Test & Measurement Equipment: High-accuracy instrumentation, such as multimeters and data acquisition modules.
• Industrial Controls: Isolated I/O interfaces and sensor signal processing in PLCs.
