GQCA025900DBT Description

The GQCA025900DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 590Ω resistance value and an ultra-tight 0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.
