GQCA012742JGT Description

The GQCA012742JGT 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 27.4KΩ with a 5% tolerance and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal conductivity and mechanical durability, making it suitable for demanding environments. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating ensure reliable operation in high-voltage circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the QSOP package optimizes board space efficiency.
