GS4A024640GFT Description

The GS4A024640GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 4-resistor isolated network features a 464Ω resistance value with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring reliable signal conditioning and voltage division. Encased in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for robust surface-mount assembly. The thin-film technology delivers excellent stability, with a low ±50ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it operates across a 70°C to 125°C derated range, with a 125°C maximum operating temperature.
