GQ8A034220BT Description

The GQ8A034220BT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers 422Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration provides robust mechanical and thermal performance, 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. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance reliability in noise-sensitive environments.
