Wurth Elektronik Openable, Diameter 5 mm Ferrite Sleeve, Apertures: 1 18.8 mm 13.2 mm 32.5 mm, For EMI Suppression

This ferrite sleeve is an openable core designed for suppression of electromagnetic interference in cable and harness assemblies. It uses material 4W620 and features a single through-aperture configuration to reduce conducted noise across a broad frequency range. The component is suitable where detachable clamp-style suppression is needed and meets RoHS and REACH standards for materials compliance.

• 92Ω impedance at 25MHz reduces low-frequency conducted interference
• 178Ω impedance at 100MHz attenuates higher-frequency emissions
• Openable design enables retrofit installation without disconnecting cables
• Single-aperture geometry supports straightforward cable routing
• 5mm aperture diameter accepts common cable sizes for suppression

• Used with signal and power cables for EMI noise reduction
• Suitable for retrofit suppression on existing cable assemblies
• Ideal for use in equipment requiring detachable noise filters
• Can be used for targeted interference suppression on single conductors
• Used with harnesses where clamping access is required

The internal bore is 5mm, enabling use with cables up to that diameter.

The 4W620 formulation provides magnetic loss characteristics suited to broadband suppression across the specified frequencies.

This design incorporates a single aperture for individual conductor suppression.

The external dimensions are 32.5mm width, 18.8mm depth and 13.2mm height to accommodate clearance.
