ABSTRACT:
A device for absorbing electrical noise on cables containing a housing comprising a pair of halfshells is disclosed. A grooved ferrite component resides within each halfshell. Flat tabs that come to rest between facing surfaces of the ferrite components when the housing is closed are formed onto the housing, thereby creating a ferrite component that has a defined air gap.
