GQ8A031132BAT Description

The GQ8A031132BAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 11.3KΩ resistance value per element with an ultra-tight 0.1% 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 dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety in critical systems.
