GQ8A021782FAT Description

The GQ8A021782FAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 17.8KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Its isolated (ISOL) circuit design allows for independent resistor functionality, making it ideal for complex circuit configurations. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network balances power handling and precision.
