GQ8B0266R5DDT

GQ8B0266R5DDT Description

The GQ8B0266R5DDT 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 66.5Ω resistance value, 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 an 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 balances power handling with compact surface-mount (SMD) design. The gull-wing termination facilitates easy PCB assembly, while the 100V maximum voltage rating makes it suitable for low-to-medium voltage circuits.
