GQ8B024990DDT Description

The GQ8B024990DDT 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 resistance value of 499Ω, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C. Encased in a ceramic package, it ensures excellent thermal stability and reliability across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it is ideal for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances its versatility in high-voltage environments.
