GQ0A021912CT Description

The GQ0A021912CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance, low temperature coefficient, and reliable isolation. This 20-pin QSOP package integrates 10 isolated resistors, each with a 19.1KΩ resistance value and an exceptional ±0.25% tolerance. The ceramic case ensures robust thermal and mechanical stability, while the gull-wing termination facilitates secure surface-mount assembly. With a 1W total power rating (0.1W per resistor) and a ±50ppm/°C temperature coefficient, this network delivers consistent performance across a wide temperature range (70°C to 125°C). Its 100V maximum voltage rating and isolated circuit design make it suitable for precision analog and digital systems.
