GS4A033161FT Description

The GS4A033161FT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 3.16KΩ resistance value with a tight ±1% tolerance and a low ±25ppm/°C temperature coefficient, this ceramic-based thin-film resistor network ensures stable performance across a wide temperature range of 70°C to 125°C. Its isolated circuit design (ISOL) allows independent resistor operation, making it ideal for precision signal conditioning and voltage division. The SOIC-C series construction offers robust mechanical stability, with a compact footprint (4.9mm x 5.99mm x 1.45mm) and gull-wing termination for reliable PCB mounting. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it balances precision with durability in harsh environments.
