GQ8A036491JBT Description

The GQ8A036491JBT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and low temperature coefficients. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 6.49KΩ resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it is engineered for demanding circuits requiring isolation (denoted by "ISOL" circuit designator). The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GQ8A036491JBT Features
