GQ8A014222FAT Description

The GQ8A014222FAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it features 42.2KΩ resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The isolated (ISOL) circuit design allows each resistor to function independently, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this component is engineered for reliability in demanding environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
