GQ8A011271JFT Description

The GQ8A011271JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-resistor isolated network features a 1.27KΩ resistance per element with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for demanding circuit designs. The gull-wing termination and surface-mount (SMD) design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A011271JFT Features
