GQ8A0247R5GDT Description

The GQ8A0247R5GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 47.5Ω resistance value with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GQ8A0247R5GDT Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±50ppm/°C) for stable operation.
• Robust Ceramic Package: Enhances thermal performance and mechanical strength in harsh environments.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive applications.
• Compact QSOP-16 Form Factor: Saves board space with 4.9mm × 6.02mm × 1.47mm dimensions and 0.64mm pitch.
• High Power Handling: Supports 0.75W total dissipation, ideal for power-sensitive designs.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).

GQ8A0247R5GDT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Industrial Control Systems: Isolated measurement and sensor interfaces requiring low drift.
• Medical Electronics: High-reliability instrumentation where consistency is critical.
• Automotive & Aerospace (non-AECQ): Non-safety-critical subsystems benefiting from ceramic robustness.
• Test & Measurement Equipment: Calibration circuits demanding tight tolerance and thermal stability.

Conclusion of GQ8A0247R5GDT

The GQ8A0247R5GDT stands out for its precision, isolation, and ceramic-packaged reliability, making it a superior choice over plastic-encapsulated networks in high-temperature or vibration-prone environments. While not PPAP or automotive-qualified, its thin-film technology and gull-wing SMD design ensure repeatable performance in industrial, medical, and instrumentation applications. Engineers will appreciate its balance of compactness, power handling, and electrical stability for critical analog designs.
