GQ8A032491JBT Description

The GQ8A032491JBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 8-resistor isolated network features a 2.49KΩ resistance value with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of 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 (1/10W) per resistor, making it suitable for compact, high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GQ8A032491JBT Features

• Precision Thin-Film Technology: Delivers stable resistance with ±25ppm/°C thermal stability, ideal for sensitive analog/digital circuits.
• Robust Ceramic Package: Ensures mechanical strength and thermal dissipation in harsh environments.
• High Power Handling: 0.75W total rating (0.1W per resistor) supports power-sensitive applications.
• Compact QSOP-16 Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• Isolated Circuit Design (ISOL): Each resistor is electrically independent, reducing crosstalk in multi-channel systems.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C).
