74271318

Overview

The Würth Elektronik 74271318 is a snap-on ferrite ring core from the WE-NCF series, designed for electromagnetic interference suppression. It features an internal diameter of 8.2 mm and utilizes 4W620 material composition. The component exhibits an impedance of 180 Ω at 25 MHz and 350 Ω at 100 MHz. Physical dimensions are 19.4 mm in length, 8.2 mm in height, and 16 mm in width. It operates within a temperature range of -25°C to +105°C.

Feature Summary

• Snap-on design with integrated nylon clamp for rapid installation on cables
• High impedance performance across specified frequency ranges
• Robust construction suitable for general electronic applications

Applications

• General EMI suppression on cables
• Power line filtering
• Data cable noise reduction

Procurement Notes

Verify the specific impedance values and physical dimensions against the official datasheet before integration. Confirm that the 8.2 mm inner diameter accommodates the target cable bundle size. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a snap-on ferrite solution is preferred over split-core or clip-on alternatives for ease of assembly. The 4W620 material offers a balance of permeability and resistivity suitable for common mode noise suppression. Consider the 8.2 mm aperture size relative to the maximum cable diameter to ensure a secure fit without excessive force during installation.
