GQ8A027320CAT Description

The GQ8A027320CAT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 732Ω resistance per element with an exceptional ±0.25% tolerance and a ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The 16-pin gull-wing SMD configuration enables reliable surface-mount assembly, while its 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs. With a 100V maximum voltage rating and non-RoHS compliance, this network is tailored for industrial and specialized environments where precision and durability are critical.
