Wurth Elektronik STAR-RING Series Ferrite Sleeve, 14.5mm Aperture Diameter, Split-Core Type - 7427151

This ferrite sleeve is an openable split-core component designed to suppress high-frequency interference on power and signal lines. It is intended for use on external power cables and internal wiring where a removable clamp is required, and it is manufactured from 4W620 material suitable for magnetic suppression tasks. The product is compatible with applications that require adherence to REACH and RoHS standards and includes a single aperture for cable routing.

Features and Benefits:

• 60Ω impedance at 25MHz reduces low-frequency interference
• 123Ω impedance at 100MHz attenuates higher-frequency noise
• Openable split core allows tool-free installation and retrofit
• High-impedance 14.5mm aperture supports common cable sizes
• Split construction enables repeated opening without cable removal

Applications

• Suitable for external power cable suppression tasks
• Used for internal cable noise reduction in enclosures
• Ideal for ferrite bead replacement on midget blind-rivet assemblies
• Can be used for point-of-entry EMI control on single cables
• Appropriate for clamp-on installation during system maintenance

What material is the clamp manufactured from?

It is MADE from 4W620 ferrite material selected for magnetic suppression properties.

How many apertures does the sleeve provide?

The component contains a single aperture sized at 14.5mm for cable passage.

Is the sleeve compliant with common chemical and hazardous substance rules?

It meets REACH and RoHS approvals for restricted substances.

Can it be installed without disconnecting cables?

Yes, the split-core openable design permits installation around live or connected cables when safe procedures allow.
