GQ8A034751GBT Description

The GQ8A034751GBT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and low thermal drift. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 4.75KΩ resistance per resistor with a tight 2% tolerance and an ultra-low ±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 (ISOL) and minimal power dissipation. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic construction enhances thermal stability and durability.
