GQ0A0251R1DDT Description

The GQ0A0251R1DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 51.1 Ω resistance and a tight 0.5% tolerance, ensuring exceptional accuracy. The ceramic case and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50 ppm/°C temperature coefficient guarantees stable performance across a wide operating range (70°C to 125°C). With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact designs.
