GQ8A021800DCT Description

The GQ8A021800DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 180Ω resistance value per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°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 superior thermal stability and reliability in harsh environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive circuits.
