GQCA013321GT Description

The GQCA013321GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP surface-mount device integrates 12 isolated resistors, each with a 3.32KΩ resistance and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The network delivers a total power rating of 1W (0.1W per resistor) and features a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a derated temperature range of 70°C to 125°C. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the QSOP package (8.66mm x 6.02mm x 1.47mm) ensures compactness.
