GQ0A021821GAT Description

The GQ0A021821GAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 1.82KΩ resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 0.64mm terminal pitch facilitates high-density PCB layouts. With a ±50ppm/°C temperature coefficient and a derated power range of 70–125°C, this network is engineered for stable performance under varying thermal conditions.
