74271733

Overview

The Würth Elektronik 74271733 is a Star-FIX Snap hinged ferrite core designed for cable noise suppression. It features an 8 mm inner diameter and measures 35.1 mm in width, 18.2 mm in height, and 21.7 mm in depth. The component utilizes 4W620 material to provide an impedance of 125 Ω at 25 MHz and 220 Ω at 100 MHz. It includes flexible cable fixing capabilities and complies with RoHS and REACH standards.

Feature Summary

• Hinged snap design allows for rapid installation onto existing cables without disconnection
• Integrated flexible cable fixing mechanism secures the clamp during operation
• Constructed from 4W620 ferrite material optimized for broadband noise attenuation

Applications

• General electronic equipment noise suppression
• Safety-related applications requiring certified components
• Cable harness EMI mitigation

Procurement Notes

Verify the specific impedance requirements against the datasheet specifications for 25 MHz and 100 MHz frequencies. Confirm that the 8 mm aperture accommodates the target cable bundle diameter. Ensure compliance with RoHS and REACH directives is required for the intended market. Check for any specific automotive or industrial certifications if applicable to the end product.

Selection Notes

Select this component when a quick-install solution is needed for cables up to 8 mm in diameter. The Star-FIX series offers superior retention compared to split-core alternatives due to its integrated fixing feature. Consider the 4W620 material properties for the specific frequency range of interference being addressed. Verify physical clearance constraints given the external dimensions of 35.1 x 18.2 x 21.7 mm.

Part Context

This part belongs to the WE-STAR-FIX Snap series from Würth Elektronik. It is distinct from the standard STAR-TEC and STAR-RING series by its unique hinged locking mechanism and integrated cable securing feature. The series is engineered for high-volume assembly environments where manual fastening tools are undesirable.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Alternative solutions may require evaluating other hinged ferrite cores with similar 8 mm apertures and comparable impedance characteristics at 100 MHz.
