GQ8A031473GFT Description

The GQ8A031473GFT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it features 147K Ohm resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. The device operates at a maximum voltage rating of 100V and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its 16-pin gull-wing SMD termination and surface-mount design make it ideal for compact PCB layouts. The ceramic case enhances thermal and mechanical durability, while the isolated (ISOL) circuit design provides flexibility in circuit configurations.
