GQ8A021871GT Description

The GQ8A021871GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.87KΩ resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers excellent thermal stability and durability. The 16-pin gull-wing SMD configuration ensures reliable surface-mount assembly, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate power applications. With a maximum voltage rating of 100V, this component is ideal for isolated circuit designs (ISOL).
