GQ0A025490CT Description

The GQ0A025490CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 10-resistor array features an isolated (ISOL) circuit design, with each resistor offering a 549 Ω resistance value at an ultra-tight 0.25% tolerance and a low ±50 ppm/°C temperature coefficient. Encased in a ceramic QSOP package, it provides excellent thermal stability and reliability across a wide temperature range of 70°C to 125°C. The 20-pin gull-wing SMD termination ensures secure surface mounting, while the 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive designs.
