GQ8A036491BT Description

The GQ8A036491BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 8-resistor array features a 6.49KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP-16 package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety in critical systems.
