GQCB0278R7JDT Description

The GQCB0278R7JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. Encased in a 24-pin QSOP (Ceramic) package, this 23-resistor array offers a 78.7Ω resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Its 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-density PCB designs requiring reliable signal conditioning or bus termination. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal and mechanical durability.

GQCB0278R7JDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances optimize space efficiency.
• Robust Construction: Ceramic case and ±50ppm/°C TCR ensure reliability in thermal cycling environments.
• Automation-Friendly: 0.64mm terminal pitch and gull-wing leads streamline SMD placement.
• High Power Handling: 1W total dissipation (derated up to 125°C) outperforms standard networks in power-intensive applications.
