Chip beads are elements that easily produce noise removal effects by being inserted in series in transmission lines, which are often sources of noise radiation. They are applied in a wide variety of instruments because of the convenience that they provide. TDK’s lineup of chip beads includes micromini products measuring at just 0.4mm×0.2mm, Gigaspira-structured products that provide high impedance at GHz bands, and products that are compatible with high currents in power lines. These products are made with TDK’s own ferrite technology and achieve effective noise removal functions at wide frequency bands. There are a great number of products available, including those that are compliant with the AEC-Q200 for in-vehicle use.
Compact size (0.6×0.3×0.3mm) that contributes to high-density mounting. In addition, these multilayer chip beads for signal lines use our original ferrite material and Gigaspira structure allowing for high impedance up to the GHz band.
