GQ0A0227R4FFT

GQ0A0227R4FFT Description

The GQ0A0227R4FFT 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 27.4Ω resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees stability across a wide operating range of -70°C to +125°C. With a maximum voltage rating of 100V and a total power dissipation of 1W (0.1W per resistor), this network is engineered for efficiency and durability in compact designs.
