GQ8B015490DBT Description

The GQ8B015490DBT 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 549 Ohm resistance value, offering a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures excellent thermal stability and reliability across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power dissipation and compactness. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its 100V maximum voltage rating makes it suitable for moderate-voltage circuits.
