GS4A023901JAT Description

The GS4A023901JAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 3.9KΩ resistance and a ±5% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient and ±0.05% ratio tolerance make it ideal for circuits requiring stable, matched resistances. The SOIC-C series construction offers 0.1W power dissipation per resistor (0.4W total), with a 100V maximum voltage rating, and is packaged in a tube for automated assembly.
