GQ0A031503GGT Description

The GQ0A031503GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 150K Ohm resistance and a tight 2% tolerance. Built with ceramic substrate and thin-film technology, it delivers excellent stability with a low ±25ppm/°C temperature coefficient. The device operates within a wide temperature range of 70°C to 125°C, derated for optimal performance, and supports a maximum voltage rating of 100V. Its gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 1W total power rating (0.1W per resistor) makes it suitable for demanding circuits.
