GUS-QS8A-02-5620-BA Description

The GUS-QS8A-02-5620-BA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing termination, this isolated network offers a 562 Ω resistance per resistor with an ultra-tight 0.1% tolerance and a low ±50 ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its compact dimensions (4.9mm length × 6.02mm depth × 1.47mm height) and 0.64mm terminal pitch make it ideal for space-constrained PCB designs.

GUS-QS8A-02-5620-BA Features

• Precision Performance: Thin film technology ensures low noise, high stability, and exact matching of resistance values.
• Robust Construction: QSOP package with gull wing leads provides mechanical durability and ease of automated assembly.
• Thermal Resilience: Derated power capability up to 125°C ensures reliability in high-temperature environments.
• Isolated Design: Circuit designator "ISOL" indicates isolated resistors, reducing crosstalk in sensitive circuits.
• Non-Automotive Grade: Suitable for industrial and commercial applications where PPAP compliance is not required.

GUS-QS8A-02-5620-BA Applications

This resistor network excels in precision analog and digital circuits, including:

• Voltage dividers and current sensing in test/measurement equipment.
• Signal conditioning for ADCs/DACs in data acquisition systems.
• Feedback networks in op-amp circuits requiring matched resistances.
• Medical devices and instrumentation where long-term stability is critical.
• Telecom infrastructure (e.g., line drivers, filters) due to its low TCR and tight tolerance.

Conclusion of GUS-QS8A-02-5620-BA

The GUS-QS8A-02-5620-BA stands out for its precision, compactness, and thermal performance, making it a superior choice for high-reliability applications. While not RoHS-compliant or automotive-grade, its thin film isolation, low TCR, and high power density cater to industrial and commercial designs requiring exact resistance matching. Engineers will appreciate its balance of miniaturization and robustness, particularly in signal chain and power management circuits.
