GS8A011581FAT

GS8A011581FAT Description

The GS8A011581FAT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding surface-mount applications. Built with ceramic substrate and thin-film technology, it delivers stable performance with a 1.58KΩ resistance per element, ±1% absolute tolerance, and an ultra-tight ±0.05% ratio tolerance. The device operates across a wide temperature range (70°C to 125°C derated, 125°C max) with a low ±100ppm/°C TCR, ensuring minimal drift in precision circuits. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.8W total) make it suitable for compact, high-density designs. The gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB assembly.
