GQ8B011272FBT Description

The GQ8B011272FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 12.7KΩ resistance value, offering 1% tolerance and a ±100ppm/°C temperature coefficient for stable performance across a 70°C to 125°C operating range. Encased in a ceramic substrate, it delivers 0.75W (3/4W) total power dissipation (0.05W per resistor), making it suitable for compact, high-density PCB designs. The gull-wing termination ensures reliable solder joints, while its 100V maximum voltage rating enhances durability in industrial and commercial circuits.
