Ferrite cores erase and filter noises, outgoing and incoming noises at the same time. There are more than a dozen different ferrite cores offered, varied by materials, and identified by two digits numbers. The ferrite cores come in two split halves, and clamp on to the cable whether it has a connector, or is hard wired to equipment. U.S. 1pc/order unless noted as a multi-quantities pack, bulk pack. TROUBLE SHOOT TIPS Install the ferrite core at the equipment side of the cable. Make as many loops as you can and/or install multiple ferrite cores until you successfully suppress offending noises. When there is a known offending noise present, making multiple loops of cable over the core is necessary. You can install the ferrite cores at affected devices, as well as at offending devices. Depending upon the circumstances, identifying and troubleshooting both the affected and offending devices are necessary. Atmospheric noises and static cannot be filtered by the ferrite cores. Only common-mode current caused noises can be filtered. Clamp on with a black plastic case RoHS Compliant Engineered in the U.S.A.
