GQ8B021051FFT

GQ8B021051FFT Description

The GQ8B021051FFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 1.05KΩ resistance value, offering a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Encased in a ceramic package, it ensures excellent thermal stability and reliability across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 0.05W per resistor, it is optimized for surface-mount (SMD) applications requiring compact, high-density circuitry. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
