GQCA035490JGT Description

The GQCA035490JGT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 549 Ω resistance value and a tight ±5% tolerance. The ceramic case construction ensures excellent thermal stability, with a temperature coefficient of ±25 ppm/°C, making it suitable for environments operating between 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and a maximum voltage rating of 100V, this surface-mount network offers reliable performance in compact designs. Its gull-wing termination facilitates easy PCB assembly, while the ±0.1mm dimensional tolerances ensure consistent placement accuracy.
