GQ8B021820DDT Description

The GQ8B021820DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a uniform 182Ω resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C. Encased in a robust ceramic package, it ensures reliable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a maximum voltage rating of 100V, this network is engineered for stability in precision circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.
