GQ8A0186R6GT Description

The GQ8A0186R6GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers an isolated (ISOL) circuit configuration, ensuring minimal crosstalk between resistors. With a resistance value of 86.6Ω per resistor and a tight 2% tolerance, it delivers consistent performance in demanding environments. The thin-film technology ensures low noise and high reliability, while the gull-wing termination facilitates easy PCB mounting. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates efficiently across a wide temperature range of -70°C to +125°C, making it suitable for both industrial and commercial applications.
