GQ0A011401DT Description

The GQ0A011401DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package integrates 10 isolated resistors, each rated at 1.4KΩ with a tight tolerance of 0.5% and a low ±100ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates reliable surface-mount assembly. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for precision analog circuits where stability and accuracy are critical.
