GQ8A034871DBT Description

The GQ8A034871DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor array features a 4.87KΩ resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±25ppm/°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 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, making it suitable for high-density circuits requiring reliable power handling. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.
