Wurth Elektronik STAR-TEC Series Ferrite Sleeve, 158Ω Impedance at 25Mhz, 278Ω Impedance at 100MHz - 74271222

This ferrite sleeve is an openable ferrite core designed for electromagnetic interference suppression in cable assemblies. It is manufactured from 4W620 material and incorporates a single through-aperture to accommodate wiring. The component is intended for in-line use where attenuation of high-frequency noise is required and is supplied with regulatory approvals for chemical and hazardous substance restrictions.

Features and Benefits:

• 158Ω impedance at 25MHz reduces mid-band conducted interference
• 278Ω impedance at 100MHz attenuates higher-frequency noise sources
• Openable split design enables retrofitting without cable disconnection
• Single 13mm aperture supports common cable diameters
• REACH and RoHS approvals indicate controlled substance compliance

Applications

• Suitable for cable EMI filter ferrite sleeve installations
• Ideal for single-cable noise suppression in signal lines
• Used with harnesses requiring openable ferrite sleeve retrofits
• Can be used for noise attenuation in electronic enclosures

What material is used for the core and why is it specified?

It is MADE from 4W620 material chosen for its magnetic properties relevant to EMI suppression.

How large is the central opening for cable routing?

The internal aperture diameter is 13mm allowing passage of single conductors or small cable bundles.

What approvals relate to environmental and hazardous substances?

The item meets REACH and RoHS approvals addressing regulated chemical content.

Can the component be fitted without disconnecting existing cables?

Yes, the openable split configuration allows installation onto cables already in place.

What are the external size constraints for mounting or enclosure space planning?

External dimensions are 42.2mm width, 33.5mm height and 28.8mm depth.
