Snap-On Ferrite Core EMI Suppressor for Power Cords and USB Cables
This snap-on ferrite core EMI suppressor is designed for EMI/RFI noise suppression on power cables and USB cables. Inner diameter ranges from 8 to 13.6mm, suitable for various round cables.
The snap-on structure requires no cable threading, allowing easy installation in retrofit and post-assembly applications. Operation is simple and convenient.
The lightweight plastic housing ensures the core is securely fixed on the cable. The precision-moulded smooth surface does not damage the cable insulation.
It is widely used in internal/external power cables, internal cables between PC boards and data connectors, computer peripherals, digital cameras, DVDs, fax machine cables, monitor cables, and printer cables.

Q: What is the difference between a snap-on ferrite core and a traditional threaded ferrite core?
A: The snap-on ferrite core has a housing that opens and closes. It can be installed without disconnecting or threading cables, making it especially suitable for already assembled cables or retrofit projects. Traditional threaded ferrite cores require pre-threading before cable end connections are made, offering less installation flexibility.
Q: How to choose the right inner diameter size?
A: Select a model with an inner diameter slightly larger than the cable outer diameter (recommend 0.5-1mm clearance). This ensures the core snaps on easily and stays securely fixed. Inner diameters range from 8-13.6mm, covering common power cable and USB cable specifications.
Q: What type of interference does this core mainly suppress?
A: This core mainly suppresses common-mode EMI, which is the same-direction noise current on live/neutral lines or signal/return lines. It is commonly used for radiated emission suppression on power cables and signal cables.
Q: Does the snap-on housing damage the cable?
A: No. The inner surface of the core is precision-moulded and smooth with no burrs, so it will not damage the cable insulation. The lightweight plastic housing provides secure fixing while protecting the cable.
