GQ8B014221DBT Description

The GQ8B014221DBT 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 4.22KΩ 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 operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.
