GQ8A027680JAT Description

The GQ8A027680JAT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 768Ω resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for demanding circuits requiring isolation (denoted by the "ISOL" circuit designator). The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.

GQ8A027680JAT Features

• Thin Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical durability in harsh environments.
• High Power Density: 0.75W total rating (0.1W per resistor) supports compact designs without sacrificing performance.
• Wide Operating Range: Rated for -70°C to +125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Precision Tolerance: 5% resistance tolerance and ±50ppm/°C TCR ensure consistent performance in signal conditioning and feedback circuits.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.

GQ8A027680JAT Applications

This resistor network excels in:

• Isolation Circuits: Signal isolation in medical equipment, test instrumentation, and industrial control systems.
• Voltage Dividers: Precision dividers in ADC/DAC interfaces or sensor signal conditioning.
• Termination Networks: High-speed data line termination (e.g., LVDS, USB) due to low parasitic effects.
• Power Supply Feedback: Stable feedback loops in DC-DC converters or voltage regulators.
• Aerospace & Defense: Non-RoHS compliance aligns with certain military or high-reliability requirements.
