Wurth Elektronik STAR-GAP Series Ferrite Sleeve, 12.5mm Aperture, Gapped - 74271622

This ferrite sleeve provides a snap-open solution for suppressing high-frequency interference on cable and signal lines. Constructed from 4W620 material with a single gapped aperture, it is designed for clamping around conductors where EMI reduction is required while remaining compliant with REACH and RoHS standards.

Features and Benefits:

• 35Ω impedance at 25MHz reduces low-frequency emissions
• 140Ω impedance at 100MHz attenuates mid-band interference
• 300Ω impedance at 300MHz targets higher-frequency noise
• 400Ω impedance at 500MHz increases suppression at VHF/UHF
• Openable snap design enables quick installation without tools

Applications

• Suitable for cable-mounted EMI suppression on signal lines
• Ideal for use where a gapped ferrite core is required
• Used with wiring that needs a 12.5mm aperture clamp
• Can be used for reducing interference in electronic assemblies
• Suitable for retrofitting existing harnesses without disconnection

How does the gapped construction affect magnetic behaviour?

The gap introduces controlled reluctance to limit core saturation and maintain suppression across varying current levels.

What aperture size is available for conductor routing?

The internal opening measures 12.5mm diameter to accommodate corresponding cable sizes.

What physical format assists Rapid deployment in assemblies?

The component is a snap ferrite clamp designed to open and close for tool-free fitting.

Which material is used for magnetic properties?

The element is manufactured from 4W620 ferrite to provide frequency-dependent impedance.

What approvals relate to material safety and substance restrictions?

The item meets both REACH and RoHS substance compliance requirements.
