GQ8A012740JT

GQ8A012740JT Description

The GQ8A012740JT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and isolation. Encased in a ceramic QSOP package, it features a 274Ω resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this 16-pin gull-wing SMD component is ideal for surface-mount PCB designs. Its isolated (ISOL) circuit design minimizes crosstalk, making it suitable for signal conditioning and analog circuits.

GQ8A012740JT Features

• Thin-film technology: Delivers high precision and low noise for sensitive applications.
• Ceramic case: Enhances thermal stability and durability in harsh environments.
• QSOP package (4.9mm x 6.02mm x 1.47mm): Compact footprint saves board space while supporting high-density layouts.
• Gull-wing terminals: Facilitates reliable soldering and inspection in automated assembly processes.
• Wide temperature range (-70°C to +125°C): Suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Non-RoHS compliant: Preferred for legacy or specialized systems requiring leaded components.

GQ8A012740JT Applications

This resistor network excels in:

• Signal isolation and termination in communication interfaces (e.g., RS-485, CAN bus).
• Voltage division and biasing in op-amp circuits and ADC/DAC systems.
• Industrial control systems where thermal stability and precision are critical.
• Medical instrumentation requiring low-drift performance over temperature.
• Legacy electronics maintenance due to its non-RoHS compliance.
