74271378

Overview

The Würth Elektronik 74271378 is a WE-NCF series split ferrite ring core designed for electromagnetic interference suppression. It features a cylindrical geometry with an internal diameter of 26.5 mm and is constructed from 4W620 material. The component provides an impedance of 200 ohms at 100 MHz and 100 ohms at 25 MHz. Its physical dimensions are 59 mm in width, 44.6 mm in height, and 35 mm in depth.

Feature Summary

• Split design allows installation on existing cables without disconnection
• Integrated nylon clamp ensures secure mechanical retention
• High-frequency noise attenuation capability

Applications

• Data line interference suppression
• Computer cable protection
• Drill handle EMI mitigation

Procurement Notes

Verify the specific part number against official Wurth Elektronik documentation to confirm material composition and dimensional tolerances. Ensure the selected variant matches the required cable diameter and impedance specifications for the target application environment.

Selection Notes

Select this component when retrofitting ferrite suppression onto cables that cannot be disconnected. The 26.5 mm aperture accommodates larger gauge wires or bundled cables. Confirm that the 4W620 material characteristics align with the frequency range of the noise being suppressed.

Part Context

This component belongs to the WE-NCF series of snap-on ferrite rings. It is distinct from solid cores as it utilizes a hinged mechanism for easy assembly. The product is categorized under ferrite cores and accessories within the manufacturer's portfolio.

Replacement Considerations
