GQ8A036812CAT Description

The GQ8A036812CAT 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 68.1kΩ resistance value per resistor with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic QSOP package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for compact, high-density designs.
