GQ8A038662CAT Description

The GQ8A038662CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 86.6K Ohm resistance value with an ultra-tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring exceptional stability across a wide operating 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 per resistor, making it suitable for high-density circuits requiring reliable power dissipation. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances durability in high-voltage environments.
