GQ8A034122BT Description

The GQ8A034122BT 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 41.2KΩ resistance value per resistor with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic QSOP package, it offers robust thermal and mechanical stability, with a maximum operating temperature of 125°C. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits.
