Wurth Elektronik Openable, Diameter 12.5 mm Ferrite Sleeve, Apertures: 1 Key 41.6 mm 28.4 mm 33.5 mm

This ferrite sleeve is an openable, snap-style choke designed to reduce cable-borne interference in electronic assemblies. It is manufactured from manganese zinc ferrite and configured with a single through-aperture to provide impedance-based attenuation across relevant RF frequencies. The component is presented in a Compact rectangular form factor suitable for retrofit or assembly use where removal or repositioning may be required.

• 140Ω impedance at 100MHz provides high-frequency attenuation
• 35Ω impedance at 25MHz delivers low-frequency suppression
• Single-aperture design enables straightforward cable installation
• Snap-open construction allows quick retrofitting and maintenance
• Non-gapped ferrite offers continuous magnetic path for EMI control

• Suitable for suppressing interference on signal and power leads
• Ideal for retrofitting existing cable harnesses in enclosures
• Used with assemblies requiring removable noise filters
• Can be used for compliance-oriented noise reduction measures

It is produced from manganese zinc ferrite to provide broadband permeability.

It contains one through-aperture for a single cable route.

Yes, the snap-open format and openable construction permit repeated fitting and removal.

No, the design is non-gapped to maintain a continuous magnetic circuit.

It conforms to RoHS and REACH chemical regulatory standards.
