74275813

Overview

The Würth Elektronik 74275813 is a snap-on ferrite core from the WE-STAR-BUENO series, designed for electromagnetic interference suppression. Constructed from 4W620 material, it features an 8.5 mm aperture and optical closing control mechanism to ensure secure closure. The component provides an impedance of 120 Ω at 1 MHz and 120 Ω at 25 MHz. It includes a security lock for enhanced electromagnetic compatibility in general electronic equipment applications.

Feature Summary

• Optical closing control mechanism ensures secure engagement
• Security lock design maintains electromagnetic compatibility integrity
• Snap-on installation facilitates rapid deployment on cables

Applications

• Electromagnetic interference suppression in general electronic equipment
• Cable shielding for digital devices requiring high-frequency noise reduction

Procurement Notes

Verify the specific impedance requirements against application frequency ranges, as the datasheet indicates 120 Ω at both 1 MHz and 25 MHz. Confirm that the 8.5 mm aperture accommodates the target cable diameter without excessive clearance. Ensure the optical closing mechanism is compatible with the assembly environment. Check for RoHS and REACH compliance documentation if required by regional regulations. Validate that the 4W620 material properties suit the operating temperature conditions.

Selection Notes

Select this component when a snap-on solution with visual confirmation of closure is required for EMI suppression. The 4W620 material offers specific permeability characteristics suitable for the stated frequency range. Consider the physical dimensions and aperture size relative to the cable bundle. The optical mechanism adds a layer of quality assurance during installation compared to standard snap cores.

Part Context

This part belongs to the WE-STAR-BUENO series of snap-on ferrite cores. It is manufactured by Würth Elektronik GmbH & Co. KG. The series is characterized by its optical closing control feature, distinguishing it from standard mechanical snap cores. It is intended for use in general electronic equipment where reliable EMI performance is critical.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided data. Consult manufacturer documentation for direct equivalents or cross-reference based on impedance, aperture, and material specifications.
