GQCA014022DBT Description

The GQCA014022DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP surface-mount device features 12 isolated resistors, each with a 40.2KΩ resistance and an ultra-tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±100ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable solder joints, while the 0.64mm terminal pitch facilitates high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits.
