GQ8A018661JAT Description

The GQ8A018661JAT 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 features 8.66KΩ resistance per resistor with a 5% tolerance and ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this surface-mount device (SMD) offers robust reliability in compact designs.
