GQ8A031470FCT Description

The GQ8A031470FCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 147Ω resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power rating (0.1W per resistor) and supports 100V maximum voltage. Its 16-pin gull-wing SMD termination and surface-mount design make it ideal for compact PCB layouts. The non-automotive, non-PPAP compliant device is supplied in tubes, catering to industrial and commercial applications.
