GQ8A014221FAT Description

The GQ8A014221FAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.22KΩ resistance value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability. The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for demanding circuits, while its 100V maximum voltage rating ensures reliability in high-voltage environments. The gull-wing termination and surface-mount design facilitate easy PCB integration.
