GQ8A0237R4JFT Description

The GQ8A0237R4JFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision isolation (ISOL) applications. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 37.4Ω resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface mounting, while the ceramic construction enhances thermal and mechanical durability.
