GQ8A013921BBT Description

The GQ8A013921BBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 3.92KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The 16-pin gull-wing SMD configuration enables reliable surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs. With a 100V maximum voltage rating and isolated (ISOL) circuit design, this network excels in precision analog and mixed-signal systems.
