GS4A026800JFT Description

The GS4A026800JFT 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 680Ω resistance and a ±5% absolute tolerance. The device operates within a temperature range of 70°C to 125°C and delivers a power rating of 0.1W per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures stable performance under thermal stress, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.
