GQ8A032872CAT Description

The GQ8A032872CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor network features a 28.7K Ohm resistance with an ultra-tight 0.25% tolerance and a low ±25ppm/°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 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances reliability in high-voltage environments.

GQ8A032872CAT Features

• High Precision: 0.25% tolerance and ±25ppm/°C TCR for consistent performance.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Compact Design: 4.9mm x 6.02mm x 1.47mm dimensions with 0.64mm terminal pitch for space-constrained layouts.
