GQ8A022101CT Description

The GQ8A022101CT 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 2.1kΩ resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device supports a maximum voltage rating 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 robustness.
