GQ8A034221JGT Description

The GQ8A034221JGT 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 4.22KΩ resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate easy surface mounting, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust performance in compact designs. Its isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for high-reliability systems.
