GQ8A031151CBT Description

The GQ8A031151CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 1.15KΩ resistance value with an ultra-tight 0.25% 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 a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its ceramic case provides excellent thermal and mechanical stability.
