GQCA025492JGT Description

The GQCA025492JGT 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 54.9kΩ 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. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 1W total power rating (0.1W per resistor) supports moderate power dissipation. With a maximum operating temperature of 125°C and a 100V voltage rating, this network is engineered for reliability in industrial and instrumentation circuits.
