GQ8A026491GT Description

The GQ8A026491GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers 6.49KΩ resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this 16-pin gull-wing SMD component is engineered for reliability in demanding environments.
