GQ0A032491JT

GQ0A032491JT Description

The GQ0A032491JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 2.49KΩ resistance value, a 5% tolerance, and a ±25ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination ensures reliable surface-mount (SMD) assembly, while the QSOP package provides compactness for space-constrained designs.

GQ0A032491JT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): 10 independent resistors prevent crosstalk, ideal for multi-channel systems.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability in harsh environments.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength compared to plastic alternatives.
• Compact QSOP Package: 8.66mm x 6.02mm footprint with a 1.47mm profile, optimized for high-density PCBs.
• Strict Tolerances: ±0.1mm length/height tolerance and ±0.2mm depth tolerance for precise placement.

GQ0A032491JT Applications

This resistor network excels in:

• Industrial Automation: Signal conditioning, PLCs, and sensor interfaces requiring stable resistance.
