GQ8A014751DBT Description

The GQ8A014751DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 4.75KΩ resistance value with an ultra-tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances versatility in industrial and instrumentation systems.

GQ8A014751DBT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR for minimal drift in critical applications.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• High Power Handling: 0.75W total power (0.1W per resistor) derated up to 125°C.
• Compact & Reliable: QSOP package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances for consistent placement.
• Isolated Design: Circuit designator "ISOL" provides electrical isolation between resistors.
• Wide Compatibility: EAR99 ECCN and non-automotive (PPAP: No) classification for broad industrial use.

GQ8A014751DBT Applications

This resistor network excels in:

• Precision analog circuits (e.g., op-amp feedback networks, voltage dividers).
• Medical instrumentation requiring stable, low-drift resistance.
• Test & measurement equipment (e.g., multimeters, signal conditioners).
• Industrial control systems where high voltage (100V) and temperature resilience are critical.
• Aerospace and defense electronics due to its ceramic-based reliability.

Conclusion of GQ8A014751DBT

The GQ8A014751DBT stands out for its precision, power efficiency, and rugged ceramic packaging, making it ideal for applications demanding long-term stability and miniaturization. While not RoHS-compliant, its thin-film technology and isolated design offer superior performance over standard thick-film networks. Engineers will appreciate its balance of compact size, high power handling, and tight tolerances, particularly in high-temperature or precision-critical environments.
