GQ8A021240GGT Description

The GQ8A021240GGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 124Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this 16-pin gull-wing SMD component is ideal for space-constrained designs requiring reliable isolation and thermal stability. Its ceramic construction enhances durability, while the QSOP package (4.9mm x 6.02mm x 1.47mm) ensures compatibility with automated assembly processes.

GQ8A021240GGT Features
