74271151

Overview

The Würth Elektronik part number 74271151S is a snap-on ferrite core belonging to the STAR-TEC series. It features an internal diameter of 10 mm and a single split opening. The component utilizes 4W620 material, providing an impedance of 64 Ω at 25 MHz and 417 Ω at 100 MHz. External dimensions are 41 mm in width, 23 mm in height, and 20 mm in depth. It includes a safety key mechanism for secure installation.

Feature Summary

• Snap-on design with integrated safety key for secure cable retention
• Utilizes 4W620 ferrite material for high-frequency noise suppression
• Single split opening configuration for rapid installation

Applications

• General electronic equipment
• Safety-related applications
• Power cables
• Computer data lines

Procurement Notes

Verify the complete part number suffix, typically 'S', which denotes RoHS compliance and halogen-free status. Confirm the specific impedance value required for the target frequency range, as the STAR-TEC series offers variants with different magnetic materials and impedance profiles. Ensure the cable diameter falls within the 10 mm internal aperture specification before ordering.

Selection Notes

Select this component when a snap-on ferrite with a locking safety key is required for vibration-prone environments. The 4W620 material provides a balanced impedance profile suitable for general EMI suppression. Compare against other STAR-TEC variants if higher impedance or different physical dimensions are needed for specific cable bundles.

Part Context

This component is part of the Würth Elektronik STAR-TEC family of snap-on ferrites. These cores are designed for quick installation on existing cables without disconnection. The series includes various internal diameters and impedance levels to accommodate different cable sizes and frequency requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting constraints and cable diameters when considering alternative snap-on ferrite solutions from other manufacturers.
