Wurth Elektronik STAR-TEC Series Ferrite Sleeve, 12.5mm Aperture, 35Ω Impedance@25MHz - 74272222
This ferrite sleeve is an openable, snap-style choke designed to reduce cable-borne interference in electronic assemblies. It is manufactured from manganese zinc ferrite and configured with a single through-aperture to provide impedance-based attenuation across relevant RF frequencies. The component is presented in a Compact rectangular form factor suitable for retrofit or assembly use where removal or repositioning may be required.
Features and Benefits:
• 140Ω impedance at 100MHz provides high-frequency attenuation
• 35Ω impedance at 25MHz delivers low-frequency suppression
• Single-aperture design enables straightforward cable installation
• Snap-open construction allows quick retrofitting and maintenance
• Non-gapped ferrite offers continuous magnetic path for EMI control
• 35Ω impedance at 25MHz delivers low-frequency suppression
• Single-aperture design enables straightforward cable installation
• Snap-open construction allows quick retrofitting and maintenance
• Non-gapped ferrite offers continuous magnetic path for EMI control
Applications
• Suitable for suppressing interference on signal and power leads
• Ideal for retrofitting existing cable harnesses in enclosures
• Used with assemblies requiring removable noise filters
• Can be used for compliance-oriented noise reduction measures
• Ideal for retrofitting existing cable harnesses in enclosures
• Used with assemblies requiring removable noise filters
• Can be used for compliance-oriented noise reduction measures
What material is used to form the magnetic core?
It is produced from manganese zinc ferrite to provide broadband permeability.
How many cable paths can it accommodate?
It contains one through-aperture for a single cable route.
Is the component suitable for frequent removal and reinstallation?
Yes, the snap-open format and openable construction permit repeated fitting and removal.
Does it include an Air gap in the magnetic path?
No, the design is non-gapped to maintain a continuous magnetic circuit.
Which environmental substance standards does it meet?
It conforms to RoHS and REACH chemical regulatory standards.
