GQCA021581JGT Description

The GQCA021581JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance characteristics. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 1.58KΩ resistance value and a 5% tolerance, ensuring reliable performance in demanding circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination facilitates easy surface-mount (SMD) assembly, while the 0.64mm terminal pitch ensures compatibility with high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for efficiency and longevity.

GQCA021581JGT Features
