GQ8A028200BAT Description

The GQ8A028200BAT 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 features 820Ω resistors with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The isolated (ISOL) circuit design eliminates crosstalk, making it ideal for precision analog and digital systems. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount device (SMD) combines reliability with compact dimensions (4.9mm x 6.02mm x 1.47mm).
