GQ8A031181CBT Description

The GQ8A031181CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 1.18KΩ resistance value per resistor with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for power-sensitive designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.
