GQ8B026490JCT Description

The GQ8B026490JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 649Ω resistance value (5% tolerance) in a compact ceramic case, offering a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor. Its thin-film technology ensures excellent stability (±50ppm/°C) and reliability across a wide temperature range (70°C to 125°C), making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances versatility.
