GQ8A028452BAT Description

The GQ8A028452BAT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers a 84.5KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 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 compact PCB layouts, while the ceramic case enhances thermal and mechanical durability.
