74272722

Overview

The Würth Elektronik 74272722 is a STAR-FIX LFS split ferrite core designed for electromagnetic interference suppression. Constructed with MnZn core material and a UL94-V0 plastic casing, it features a hinged design requiring a key for operation. The component provides an impedance of 40 Ohms at 10MHz and 55 Ohms at 25MHz. It has a circular shape with a 12.5mm internal diameter and external dimensions of 31.00mm width, 28.00mm height, and 35.10mm length. The part is RoHS and REACH compliant.

Feature Summary

• Patented flexible cable fixing mechanism ensures secure attachment to cables
• Hinged snap design requires a specific key for opening and closing
• MnZn core material optimized for high-frequency noise attenuation
• UL94-V0 rated plastic casing for fire safety compliance

Applications

• Electromagnetic interference suppression on cables
• Cable clamping protection in electronic assemblies
• High-frequency noise filtering in automotive components

Procurement Notes

Verify the exact part number 74272722 against official Wurth Elektronik documentation to confirm specifications. Check current manufacturing status as this item may be obsolete or discontinued. Ensure compatibility with the required cable diameter range of 8.5-12.5mm before procurement. Confirm RoHS and REACH compliance requirements for your specific application standards.

Selection Notes

Select this component when a hinged ferrite core with a safety lock is required for post-installation cable routing. The STAR-FIX LFS series is suitable for applications needing secure cable fixation without permanent modification. Consider the 12.5mm inner diameter constraint and the need for a key tool during installation. Evaluate impedance requirements at target frequencies against the 40 Ohm @ 10MHz specification.

Part Context

This component belongs to the STAR-FIX LFS family of snap ferrites from Würth Elektronik. These cores utilize patented technology for flexible cable fixing and clamping protection. The series is designed for easy installation on existing cables using a hinged mechanism. It serves as a passive component for EMC filtering in various industrial and automotive contexts.

Replacement Considerations

Public records indicate that part number 74272222 is associated with this product line. Verify if alternative split ferrite cores from the same manufacturer meet the dimensional and impedance requirements. Cross-reference datasheets for equivalent MnZn materials and locking mechanisms.
