GQ8A0227R4FCT Description

The GQ8A0227R4FCT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) circuit applications. Housed in a 16-pin QSOP ceramic package, it offers a 27.4Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this surface-mount device (SMD) is engineered for reliability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.
