74271358

Overview

The Würth Elektronik part number 74271358 is a cylindrical ferrite ring core from the WE-NCF series, constructed with 4W620 material. It features an integrated nylon clamp to facilitate installation on cables. The component provides an impedance of 98 Ohms at 100 MHz and 382 Ohms at 25 MHz. Key physical dimensions include an inner diameter of 10 mm, an outer diameter of 20 mm, and a length of 15 mm. It operates within a temperature range of -25°C to +105°C.

Feature Summary

• Integrated nylon clamp design for secure cable attachment
• High permeability 4W620 ferrite material composition
• Cylindrical geometry optimized for round cable applications

Applications

• Suppression of common mode noise on power cables
• EMI reduction in computer data transmission lines
• Filtering electromagnetic interference in general electronic assemblies

Procurement Notes

Verify the specific impedance curve against application frequency requirements using official datasheets. Confirm that the nylon clamp integrity meets environmental standards for the intended operating temperature range. Ensure cable diameters fall strictly within the specified inner diameter tolerance to maintain effective magnetic coupling and mechanical retention.

Selection Notes

Select this component when a snap-on solution is required for existing cabling without disconnection. Compare impedance characteristics against other WE-NCF variants to match specific noise frequencies. Consider the physical size constraints of the assembly space relative to the 20 mm outer diameter and 15 mm length specifications.

Part Context

This component belongs to the WE-NCF series of snap-on ferrite cores designed for rapid deployment on wires and cables. The series utilizes high-permeability materials to provide effective broadband noise suppression. The integration of a plastic clamp distinguishes it from split-core designs requiring tools or adhesive for installation.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Engineers should consult manufacturer cross-reference guides for equivalent impedance profiles and dimensional compatibility.
