GQCA021473GFT Description

The GQCA021473GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 24-pin QSOP device integrates 12 isolated resistors, each rated at 147KΩ with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal management and durability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the QSOP package (8.66mm x 6.02mm x 1.63mm) optimizes board space.
