Ferrite Sleeves Applications Wurth Elektronik axial ferrite rings fit over the cable, absorbing energy emitted by cables without affecting the transmitted data. These ferrite rings can be fixed on the cable by using heat shrink sleeving. Attenuation is better than ferrite rings owing to the increased ferrite level, and is increased by threading the cable through several times Wires
