GQ8A031331FT Description

The GQ8A031331FT 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 a 1.33KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, this 16-pin gull-wing SMD component is ideal for space-constrained designs requiring reliable isolation and minimal thermal drift. Its 100V maximum voltage rating and isolated (ISOL) circuit design make it suitable for demanding environments.
