GS4A031540FT Description

The GS4A031540FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 154Ω resistance and a tight ±1% tolerance. Built with ceramic substrate technology, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations facilitates easy surface-mount assembly, while its 100V maximum voltage rating and 0.1W power rating per resistor make it suitable for demanding circuits.
