GQCA022942JFT Description

The GQCA022942JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each rated at 29.4KΩ with a 5% tolerance and a ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal conductivity and mechanical durability, making it suitable for demanding environments. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for reliability in both industrial and commercial circuits. Its gull-wing termination ensures secure surface-mount (SMD) attachment, while the 100V maximum voltage rating accommodates moderate to high-voltage designs.
