GQ8A024700GAT Description

The GQ8A024700GAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers 470Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex circuit configurations. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network balances power handling and compactness (4.9mm × 6.02mm × 1.47mm).

GQ8A024700GAT Features

• Thin-film technology: Delivers superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
• Ceramic QSOP package: Enhances thermal performance and mechanical durability in harsh environments.
• Gull-wing termination: Facilitates robust surface-mount assembly with a 0.64mm terminal pitch for high-density PCB layouts.
• Wide derated power range: Operates at full power up to 70°C, derating linearly to 125°C, ensuring consistent performance under thermal stress.
• Non-automotive, non-PPAP: Suitable for industrial, telecom, and instrumentation applications where automotive-grade certification isn’t required.
• Tube packaging: Protects components during handling and assembly.

GQ8A024700GAT Applications

This resistor network excels in:

• Precision analog circuits: Voltage dividers, feedback networks, and sensor conditioning in test/measurement equipment.
• Signal isolation: Isolated signal paths in communication interfaces (e.g., RS-485, CAN bus).
• Power management: Current-limiting and bias networks in DC/DC converters or power supplies.
• Industrial controls: PLCs, motor drives, and automation systems requiring stable resistance under thermal cycling.
• Medical electronics: Diagnostic devices where low drift and accuracy are critical.

Conclusion of GQ8A024700GAT

The GQ8A024700GAT stands out for its combination of precision, power efficiency, and rugged ceramic packaging. While not RoHS-compliant, its thin-film construction and isolated design make it a preferred choice for engineers prioritizing performance in non-automotive, high-reliability applications. Its compact QSOP form factor and gull-wing terminals further simplify integration into space-constrained designs, offering a compelling alternative to discrete resistors in network-optimized circuits.
