GQ0A0227R4DCT Description

The GQ0A0227R4DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 27.4 Ω resistance value and a tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50 ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 0.64 mm terminal pitch facilitates high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision signal conditioning and voltage division in industrial and instrumentation systems.
