GQCA022942GFT Description

The GQCA022942GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP surface-mount device features 12 isolated resistors, each with a 29.4kΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±50ppm/°C temperature coefficient. The gull-wing termination facilitates reliable PCB mounting, while the 0.1W power rating per resistor (1W total) makes it suitable for low-power, high-density designs.
