GS4A0268R0FT

GS4A0268R0FT Description

The GS4A0268R0FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 68Ω resistance and a tight ±1% tolerance. Operating within a temperature range of 70°C to 125°C, it delivers 0.1W (1/10W) power rating per resistor (0.4W total), ensuring reliable performance in demanding environments. The ±50ppm/°C temperature coefficient enhances stability, while the 100V maximum voltage rating and gull-wing termination facilitate robust surface-mount (SMD) integration. Its ceramic case ensures durability, and the SOIC package (4.9mm x 5.99mm x 1.45mm) offers compactness for space-constrained designs.
