GS4A035111FT Description

The GS4A035111FT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation (ISOL) applications. Housed in an 8-pin narrow SOIC package with a ceramic case style, it features thin-film technology for stable performance. Each resistor offers a 5.11KΩ value with a tight ±1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliability across a 70°C to 125°C derated power range. The device operates at up to 125°C with a 100V maximum voltage rating and delivers 0.1W (1/10W) per resistor (0.4W total). Its gull-wing termination and surface-mount design (4.9mm x 5.99mm x 1.45mm) suit automated assembly.
