GQ8A0278R7JGT Description

The GQ8A0278R7JGT 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. Housed in a 16-pin QSOP ceramic package, it offers a 78.7Ω resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this isolated network is ideal for demanding circuits where space efficiency and thermal management are critical. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and heat dissipation.

GQ8A0278R7JGT Features

• Thin Film Technology: Delivers superior stability, low noise, and tight tolerance (±5%) compared to thick-film alternatives.
• High Power Handling: 0.1W per resistor (0.75W total) enables use in power-sensitive designs without derating concerns.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive environments (though non-automotive PPAP).
• Compact QSOP Package: 4.9mm x 6.02mm footprint with a 1.47mm profile, ideal for high-density PCBs.
• Isolated Design (ISOL): Each resistor is electrically independent, offering flexibility in circuit design.
• Ceramic Construction: Provides excellent thermal conductivity and mechanical strength vs. plastic-bodied networks.

GQ8A0278R7JGT Applications
