GQ8B0148R7FDT Description

The GQ8B0148R7FDT 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 48.7Ω resistance value, offering a tight 1% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures stability across a wide operating temperature range (70°C to 125°C) and supports a maximum voltage rating of 100V. With a total power rating of 0.75W (3/4W) and 0.05W per resistor, it balances compactness with robust performance. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
