GS4A032742DAT

GS4A032742DAT Description

The GS4A032742DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying environmental conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features thin-film technology with a 27.4KΩ resistance value and an exceptional ±0.5% absolute tolerance (±0.05% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -55°C to +125°C, making it suitable for precision analog and digital circuits. The SOIC-C series construction provides robust ceramic isolation, enhancing reliability in high-voltage environments (up to 100V). With a 0.1W power rating per resistor (0.4W total) and gull-wing termination, it is optimized for surface-mount assembly in compact PCB layouts.
