GQ8A017871FAT Description

The GQ8A017871FAT 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 7.87KΩ resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex circuit designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in demanding environments. Its 16-pin gull-wing SMD termination ensures secure surface mounting, while the ceramic case enhances thermal and mechanical durability.
