GQ8A027322DBT Description

The GQ8A027322DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 73.2K Ohm resistance per element with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) save board space.

GQ8A027322DBT Features

• Precision Performance: 0.5% tolerance and ±50ppm/°C TCR for minimal drift in critical applications.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Isolated Design: Circuit designator "ISOL" indicates individual resistor isolation, reducing crosstalk.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch for reliable SMD assembly.
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP or automotive-grade.
