7427248

Overview

The Wurth Elektronik 7427248 is a snap-on ferrite core from the STAR-FLAT series, designed for flat ribbon cables. It features a grey housing made of 4W620 material and incorporates safety key technology to ensure secure closure. The component measures 71.3 mm in length, 33.1 mm in width, and 16 mm in height. It provides an impedance of 180 Ohms at 100 MHz and 78 Ohms at 25 MHz. The product complies with RoHS and REACH standards.

Feature Summary

• Incorporates safety key technology to guarantee electromagnetic compatibility through a secure locking mechanism.
• Designed specifically for flat ribbon cable applications to suppress electromagnetic interference.
• Constructed from 4W620 material housed in a grey snap-on casing.

Applications

• Electromagnetic interference suppression for flat ribbon cables
• General electronic equipment requiring EMC compliance

Procurement Notes

Verify the specific impedance values and physical dimensions against the official datasheet before integration. Confirm that the safety key mechanism aligns with your assembly requirements. Ensure the part number matches the exact STAR-FLAT variant required for your flat cable geometry. Check for updated compliance certifications such as RoHS and REACH status.

Selection Notes

Select this component when managing flat ribbon cables rather than round wires. The integrated safety lock prevents accidental opening during operation. Consider the 180 Ohm impedance at high frequencies for effective noise reduction. Verify that the internal clearance accommodates the specific thickness of the target flat cable bundle.

Part Context

This part belongs to the STAR-FLAT series of snap-on ferrites by Wurth Elektronik. It is distinct from round wire cores like the STAR-RING or STAR-TEC series due to its rectangular cross-section. The design prioritizes secure attachment on flat conductors where standard split cores might not fit or stay closed effectively.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Compare internal dimensions and impedance curves carefully if considering alternative manufacturers.
