GQ8B014750DT Description

The GQ8B014750DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 475Ω resistance value, offering a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic package, it ensures superior thermal stability and durability. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a maximum operating temperature of 125°C, it excels in environments requiring reliable performance under thermal stress. The gull-wing termination facilitates easy surface-mount (SMD) assembly, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
