7427141S

Overview

The Würth Elektronik 7427141S is a snap-on ferrite core from the STAR-TEC series, designed for EMI suppression on cables. It features a hinged design with a key for secure closure and an internal diameter of 5 mm. The component utilizes 4W620 material to provide high impedance in the MHz range. Key electrical parameters include an impedance of 182 Ω at 100 MHz and 64 Ω at 25 MHz. Physical dimensions are 32.5 mm length, 13.2 mm width, and 18.8 mm height. It complies with RoHS and REACH standards.

Feature Summary

• Hinged snap-on design with a dedicated key for secure installation
• Utilizes 4W620 ferrite material for effective noise suppression
• Free-hanging cable mounting configuration

Applications

• General electronic equipment
• Safety-related applications
• Power supply cables

Procurement Notes

Verify the specific suffix 'S' indicates the inclusion of the locking key, as this affects physical installation requirements. Confirm that the 4W620 material composition aligns with the target frequency spectrum for electromagnetic interference reduction. Ensure the 5 mm inner diameter accommodates the specific cable gauge intended for the application without excessive strain on the housing.

Selection Notes

Select this component when a compact, quick-installation solution is required for cables up to 5 mm in diameter. The STAR-TEC series offers a balance between mechanical robustness and magnetic performance. Consider the 182 Ω impedance at 100 MHz for broadband noise attenuation needs. Verify that the free-hanging installation method is compatible with the mechanical constraints of the final assembly environment.

Part Context

This part belongs to the Würth Elektronik STAR-TEC series of snap-on ferrites. These components are engineered for rapid deployment on existing wiring harnesses. The series provides various inner diameters and impedance profiles to suit different cable sizes and frequency requirements while maintaining compliance with international environmental directives.

Replacement Considerations

Direct substitutes within the same series include part number 74271142S, which shares identical 5 mm aperture and dimensional specifications. Both parts utilize the same 4W620 material and offer comparable impedance characteristics. Ensure the replacement retains the hinged mechanism and key requirement for proper closure.
