GQ8A017321BT Description

The GQ8A017321BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor network features a 7.32KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (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 enables reliable surface-mount assembly, while the 100V maximum voltage rating and 0.75W total power dissipation make it suitable for high-reliability circuits.
