GS8A031803CAT Description

The GS8A031803CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying environmental conditions. This 16-pin narrow SOIC package features 8 isolated thin-film resistors, each with a 180KΩ resistance and an exceptional ±0.25% absolute tolerance (±0.05% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, with a ±25ppm/°C temperature coefficient, ensuring minimal drift in critical circuits. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.8W total) make it suitable for precision analog and digital systems. The SOIC-C series construction provides robust ceramic encapsulation, enhancing durability and thermal stability.
