Wurth Elektronik STAR-RING Series Ferrite Sleeve, 27mm Aperture, High Impedance - 7427155

This ferrite sleeve is a clamp-on EMI suppression component designed to reduce common-mode interference on cable assemblies. It is manufactured from a 4W620 ferrite material and includes a keyed snap mechanism to secure it around conductors. The device provides impedance across a broad RF range, enabling improved signal integrity in electronic systems where suppression of conducted noise is required.

Features and Benefits:

• 54Ω impedance at 25MHz reduces low-frequency conducted interference
• 112Ω impedance at 100MHz attenuates higher-frequency noise
• Snap-on keyed design allows tool-free installation
• Clamp-style construction enables retrofitting to existing cables
• Ferrite composition tailored for EMI/RFI attenuation performance

Applications

• Suitable for suppression on power and data cable runs
• Ideal for reducing interference in control panels
• Used with harnesses in industrial electronic equipment
• Can be used for noise reduction near sensitive receivers
• Appropriate for retrofit EMC mitigation on installed wiring

What physical feature secures the component to a cable?

It incorporates a keyed snap mechanism that locks the two halves together to maintain position on a cable.

How does its impedance behaviour assist in noise suppression?

The impedance increases with frequency, providing greater attenuation of higher-frequency interference while still offering suppression at lower RF bands.

What is the principal material used and its role?

The part is formed from 4W620 ferrite, selected for its magnetic properties that convert unwanted electrical noise into heat within the material.

Can it be fitted without disconnecting wiring?

Yes, the clamp-style snap design permits installation around existing conductors without the need to reterminate connections.
