GQ8A0166R5DT Description

The GQ8A0166R5DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. This 8-resistor isolated network features a 66.5Ω resistance value with an exceptional ±0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
