GQ8A0166R5FT Description

The GQ8A0166R5FT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it offers a 66.5Ω resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for applications requiring individual resistor control. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
