GQ8B0148R7GT Description

The GQ8B0148R7GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. Encased in a 16-pin QSOP ceramic package, it integrates 15 resistors with a 48.7Ω resistance value, 2% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.05W per resistor, this network is engineered for reliability in compact, high-density circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate seamless PCB integration, while the ceramic case enhances thermal and mechanical durability.
