GQ8A034701CT Description

The GQ8A034701CT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it offers a 4.7KΩ resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device supports a maximum voltage rating of 100V and delivers 0.1W (1/10W) power dissipation per resistor, with a total power rating of 0.75W (3/4W). Its gull-wing termination and surface-mount design make it suitable for automated PCB assembly. The ceramic case enhances thermal performance, while the QSOP package (4.9mm x 6.02mm x 1.47mm) ensures compactness for space-constrained designs.
