74271338

Overview

The Würth Elektronik 74271338 is a snap-on ferrite ring core from the WE-NCF series, designed for electromagnetic interference suppression. It features a circular shape with an internal diameter of 17.00 mm and external dimensions of 32.20 mm width by 10.20 mm height. The component utilizes 4W620 ferrite material to provide an impedance of 114 Ohms at 100 MHz. It includes a nylon clamp for secure base installation on cables.

Feature Summary

• Integrates a nylon clamp for secure attachment to cables
• Utilizes 4W620 ferrite material for effective noise suppression
• Designed for base installation applications

Applications

• Electromagnetic interference suppression on cables
• Base installation in electronic assemblies
• General EMI filtering applications

Procurement Notes

Verify the specific part number 74271338 against official Wurth Elektronik documentation to confirm the 114 Ohm impedance at 100 MHz and 17.00 mm inner diameter. Ensure the nylon clamp inclusion matches project requirements. Cross-reference datasheets for RoHS compliance and operating temperature ranges before finalizing procurement specifications.

Selection Notes

Select this component when a snap-on ferrite solution with integrated clamping hardware is required for cable management. The 17.00 mm aperture accommodates specific cable bundles. Consider the 114 Ohm impedance profile at 100 MHz for target frequency attenuation needs. Verify physical clearance for the 32.20 mm x 10.20 mm footprint during mechanical design integration.

Part Context

This component belongs to the WE-NCF series of ferrite cores manufactured by Würth Elektronik. The series focuses on snap-on designs that simplify assembly processes compared to split-core alternatives requiring separate fasteners. The 4W620 material composition is optimized for high-frequency noise reduction in compact form factors suitable for modern electronic equipment.
