GQ8A0247R5FCT Description

The GQ8A0247R5FCT 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 47.5Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The device features gull-wing SMD terminations with a 0.64mm pitch, optimized for automated PCB assembly. Its 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating make it suitable for demanding circuits requiring precision and reliability.
