GQ0A011911DT Description

The GQ0A011911DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 10-resistor array features a 1.91KΩ resistance value with a 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 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm × 6.02mm × 1.47mm) save board space.

GQ0A011911DT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR ensure accuracy in critical applications.
• Robust Construction: Ceramic case enhances thermal stability and durability.
• High Power Handling: 1W total power rating (0.1W per resistor) supports demanding circuits.
• Space-Efficient: QSOP package with 20 gull-wing terminals optimizes PCB layout.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Isolated Design: Circuit designator "ISOL" indicates isolated resistors, reducing crosstalk.

GQ0A011911DT Applications

This resistor network is ideal for:

• Precision analog circuits (e.g., sensor interfaces, DAC/ADC networks).
• Industrial control systems requiring stable resistance under thermal stress.
• Medical electronics where accuracy and reliability are critical.
• Telecommunications equipment (e.g., signal conditioning, impedance matching).
• Automotive test/validation systems (though not PPAP/AEC-Q200 qualified).

Conclusion of GQ0A011911DT

The GQ0A011911DT combines high precision, robust packaging, and excellent thermal performance, making it a standout choice for engineers designing high-reliability, space-constrained applications. Its ceramic QSOP construction and isolated thin-film resistors offer superior stability over alternatives, particularly in industrial, medical, and telecom systems. While not automotive-grade, its 0.5% tolerance and low TCR ensure consistent performance in precision-critical environments.
