Wurth Elektronik Openable, Diameter 8.5 mm Ferrite Sleeve, Apertures: 1 56.2 mm 24 mm 24 mm, For EMI Suppression

This ferrite sleeve is an openable Snap-on ferrite core designed for electromagnetic interference suppression in wiring assemblies. It is manufactured from 4W620 material and provides a single 8.5mm aperture to accommodate cables or harnesses. The component is compliant with RoHS and REACH standards and is supplied in a clamp-style form factor suitable for retrofitting into existing installations.

• 171Ω impedance at 25MHz reduces low-frequency conducted noise
• 340Ω impedance at 100MHz attenuates higher-frequency interference
• Openable snap design enables Rapid installation without cable disconnection
• Single-aperture construction simplifies placement on individual conductors
• 24x24mm external footprint suits Compact wiring assemblies

• Suitable for attenuation of cable-borne EMI in control panels
• Ideal for use on signal wiring in industrial equipment
• Used with harnesses requiring retrofittable noise suppression
• Can be used for point-of-entry suppression on incoming cables
• Suitable for reducing RFI in sensitive measurement circuits

The component provides one 8.5mm aperture intended for a single conductor or a small bundled group depending on conductor diameters.

The ferrite is MADE from 4W620 material, which determines frequency-dependent impedance and loss behaviour across the specified bands.

Its Snap-on clamp form allows it to be fitted around existing wiring without disconnecting terminations, simplifying upgrades and maintenance.

The outer dimensions measure 24x24mm with a depth of 56.2mm, which should be allowed for when planning enclosure or cable-loom placement.
