GUS-QS8B-03-4120-GF Description

The GUS-QS8B-03-4120-GF 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 15 resistors with a 412Ω resistance value, offering a 2% tolerance and a low ±25ppm/°C temperature coefficient for stable operation across a wide -70°C to +125°C range. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it balances compact dimensions (4.9mm × 6.02mm × 1.47mm) with robust performance. The gull-wing termination ensures reliable solder joints in automated SMD processes, while the tube packaging facilitates handling during production.

GUS-QS8B-03-4120-GF Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• High-Density Integration: 15 resistors in a compact QSOP-16 package, saving board space.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• Low TCR (±25ppm/°C): Minimizes resistance drift in fluctuating thermal environments.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch simplify pick-and-place assembly.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance isn’t required.

GUS-QS8B-03-4120-GF Applications

This resistor network excels in:

• Signal Conditioning Circuits: Voltage dividers, pull-up/pull-down networks in precision analog systems.
• Medical Electronics: Patient monitoring devices requiring stable, low-drift resistance.
• Test & Measurement Equipment: Calibration circuits and sensor interfaces.
• Industrial Control Systems: PLCs and motor drivers where temperature resilience is critical.
• Telecom Infrastructure: RF modules and baseband processing units needing tight tolerance matching.
