Wurth Elektronik STAR-RING Series Ferrite Ring, 27mm Aperture Diameter, Openable Snap Ferrite - 7427155S


This ferrite ring is an openable Snap-on ferrite designed to reduce electromagnetic interference on conductors. It is manufactured from 4W620 ferrite material and intended for both general and safety-relevant applications. The component features a single aperture and a snap-fit design to allow simple retrofitting to existing cabling without disconnecting circuits.

Features and Benefits:


• 54Ω impedance at 25MHz delivering mid-frequency suppression
• 112Ω impedance at 100MHz providing higher-frequency attenuation
• Openable Snap-on design enabling tool-free installation
• Single-aperture form allowing individual cable choking
• RoHS and REACH-compliant materials supporting regulatory needs

Applications


• Suitable for suppression of cable-borne EMI in equipment
• Ideal for retrofit on signal and power lines
• Used with harnesses requiring one-pass noise attenuation
• Can be used for components in safety-relevant circuits
• Suitable for assemblies needing snap ferrite 27mm aperture

How is the component fitted onto existing cables?


It clips open around a conductor using its Snap-on geometry, allowing installation without cable disconnection.

What material properties affect magnetic performance?


The 4W620 ferrite composition provides permeability characteristics tailored to EMI attenuation across mid-to-high MHz bands.

What approvals indicate chemical and environmental restrictions conformity?


The part meets RoHS and REACH substance restrictions, ensuring reduced hazardous material content.

How many cables can be routed through the aperture at once?


The single aperture accommodates one conductor or a grouped bundle sized to the 27mm internal diameter.

What size envelope should designers allow for board or chassis clearance?


Allocate space for external dimensions of 55 x 44 x 20mm to ensure unimpeded mounting and closure.
