GQCA011780GT

GQCA011780GT Description

The GQCA011780GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 178Ω resistance value and a tight 2% tolerance. Encased in a ceramic substrate, it offers superior thermal stability and durability, with an operating temperature range of 70°C to 125°C (derated) and a maximum rating of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 0.64mm terminal pitch facilitates high-density PCB layouts. With a ±100ppm/°C temperature coefficient and 100V maximum voltage rating, this network delivers consistent performance in demanding environments.
