GQ8B029102GFT Description

The GQ8B029102GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 91kΩ resistance value and a tight 2% tolerance. Built on a ceramic substrate, it offers excellent thermal stability with a ±50ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 0.64mm terminal pitch supports high-density layouts. With a 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for demanding circuits. Packaged in a tube, it is ideal for prototyping and automated assembly.
