GQCA0127R0DCT Description

The GQCA0127R0DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 27Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in voltage division and impedance matching. Encased in a ceramic substrate, it offers superior thermal stability and mechanical robustness, with a maximum operating temperature of 125°C and a power rating of 1W (0.1W per resistor). Its gull-wing termination and surface-mount design facilitate automated PCB assembly, while the ±100ppm/°C temperature coefficient ensures minimal drift across a wide 70°C to 125°C derated power range.
