GQ8A0140R2DDT Description

The GQ8A0140R2DDT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it offers a 40.2Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The device supports a maximum operating voltage of 100V and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical reliability.
