GQ8A011540FT Description

The GQ8A011540FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low tolerance. This 8-resistor isolated network features a 154 Ω resistance per element with a tight 1% tolerance and a ±100 ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and supports 100V maximum voltage rating. Its 16-pin gull-wing SMD termination and surface-mount design make it ideal for automated assembly processes.

GQ8A011540FT Features
