GS4A026802JFT Description

The GS4A026802JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a 68 kΩ resistance and a ±5% absolute tolerance. Its ±50 ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this network is engineered for reliability in compact, surface-mount designs. The gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.
