GS4A027682FAT

GS4A027682FAT Description

The GS4A027682FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 76.8KΩ and a tight ±1% absolute tolerance (with ±0.05% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, ensuring stability in harsh environments. With a ±50ppm/°C temperature coefficient, it delivers exceptional thermal performance, while the 0.1W (1/10W) power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.
