GQ0B0278R7JDT Description

The GQ0B0278R7JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 78.7Ω resistance value and a 5% tolerance, ensuring reliable signal integrity and minimal deviation. Encased in a ceramic substrate, the network offers superior thermal stability and mechanical durability, making it suitable for environments with elevated temperatures up to 125°C. The gull-wing termination style facilitates easy surface-mount (SMD) assembly, while the 0.64mm terminal pitch ensures compatibility with high-density PCB layouts. With a ±50ppm/°C temperature coefficient and a 1W total power rating (0.05W per resistor), this component balances precision with robust power handling.
