GQCA011820GGT Description

The GQCA011820GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 182Ω resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability and mechanical durability, making it suitable for demanding environments. With a ±100ppm/°C temperature coefficient, it maintains consistent performance across a wide temperature range (70°C to 125°C). The gull-wing termination ensures secure surface-mount attachment, while the 0.64mm terminal pitch facilitates high-density PCB layouts.
