GQ0A031150GT Description

The GQ0A031150GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 10-resistor isolated network features a 115Ω resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating further enhance its versatility in circuit designs requiring isolation and precision.

GQ0A031150GT Features

• Thin-Film Technology: Delivers superior accuracy, stability, and low noise compared to thick-film alternatives.
• Ceramic QSOP Package: Provides robust mechanical strength and thermal performance, ideal for high-reliability applications.
• Gull Wing Termination: Ensures secure surface-mount (SMD) attachment with a 0.64mm terminal pitch for compact PCB layouts.
• Isolated Circuit Design (ISOL): Each resistor is electrically independent, enabling flexible circuit configurations.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C), suitable for industrial and automotive-adjacent uses.
• Non-Automotive PPAP: While not PPAP-certified, its precision makes it ideal for test equipment, medical devices, and telecom infrastructure.

GQ0A031150GT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces where stability is critical.
• Industrial Control Systems: PLCs, motor drives, and power supplies requiring isolated resistance paths.
• Communications Hardware: RF modules, signal conditioning, and impedance matching in base stations.
• Medical Electronics: Patient monitoring and diagnostic equipment demanding low drift over temperature.
• Test & Measurement: Calibration tools and data acquisition systems benefiting from ±25ppm/°C TCR.

Conclusion of GQ0A031150GT

The GQ0A031150GT stands out for its combination of thin-film precision, ceramic ruggedness, and isolated design, offering engineers a reliable solution for high-accuracy applications.
