GQ8A028202DAT Description

The GQ8A028202DAT 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 82K Ohm resistance per element with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. Rated for 0.75W (3/4W) total power and 100V maximum voltage, this 16-pin gull-wing SMD device is ideal for space-constrained PCB designs. Its isolated (ISOL) circuit design minimizes crosstalk, while the ceramic substrate enhances thermal performance and durability. Packaged in a tube, it suits automated assembly processes.
