GQ8A0278R7GGT Description

The GQ8A0278R7GGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it features 78.7Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD termination enables reliable surface mounting, while the 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating make it suitable for demanding circuits. Its isolated (ISOL) circuit design provides flexibility in configurations. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for prototyping and low-to-mid-volume production.

GQ8A0278R7GGT Features

• Precision Thin Film Technology: Delivers stable performance with ±50ppm/°C TCR and 2% tolerance.
• Robust Construction: Ceramic QSOP case ensures durability and thermal stability.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) for energy-efficient designs.
