GQ8A0351R1FDT Description

The GQ8A0351R1FDT 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 51.1Ω 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 device features gull-wing SMD terminations for reliable surface mounting, with a 0.64mm terminal pitch and compact dimensions (4.9mm x 6.02mm x 1.47mm). Its ceramic case provides superior thermal and mechanical stability, while the 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating make it suitable for demanding circuits.
