GQ8A031300FFT Description

The GQ8A031300FFT is a high-precision, 8-resistor thin-film network from TT Electronics/IRC, designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it offers a 130Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for demanding circuits, while its 100V maximum voltage rating and gull-wing SMD termination enable reliable surface mounting in compact designs. The ceramic case provides excellent thermal stability and durability, though it is non-compliant with EU RoHS.
