GS8A011201CAT Description

The GS8A011201CAT from TT Electronics/IRC is a high-precision 8-resistor isolated network housed in a 16-pin narrow SOIC ceramic package. Designed for demanding applications, it features 1.2KΩ thin-film resistors with an absolute tolerance of ±0.25% and a ratio tolerance of ±0.05%, ensuring exceptional accuracy. The device operates over a wide temperature range (70°C to 125°C @ derated power) with a ±100ppm/°C temperature coefficient, making it stable under thermal stress. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.8W total) suit precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances durability and thermal performance.
