74270106

Overview

The Würth Elektronik 74270106 is a cylindrical ferrite core from the WE-TOF series, designed for EMI suppression. It features an internal diameter of 7.1 mm and an outer diameter of 13.2 mm, with a total length of 12.7 mm. The component exhibits an impedance of 107 ohms at 100 MHz. Constructed from specific ferrite material optimized for high-frequency noise attenuation, it serves as a passive electromagnetic interference filter for cables and wires.

Feature Summary

• Cylindrical geometry facilitates easy installation onto existing cables without disconnection
• Provides effective common-mode noise suppression in high-frequency applications
• Designed for direct clamping onto conductors to attenuate electromagnetic interference

Applications

• Suppression of electromagnetic interference on data cables
• Noise filtering for power supply lines
• EMI mitigation in automotive electronic wiring harnesses

Procurement Notes

Verify the specific part number suffix against official Wurth Elektronik documentation to ensure correct impedance characteristics and material composition. Confirm that the internal diameter matches the target cable size prior to integration. Cross-reference the manufacturing date code with current RoHS compliance declarations to ensure adherence to environmental standards required for the intended deployment region.

Selection Notes

Select this component when a cylindrical form factor is preferred over snap-fit rings for retrofitting or space-constrained cable management. Evaluate the 107-ohm impedance profile against the specific frequency spectrum of the noise source to ensure adequate attenuation. Consider the physical dimensions relative to the available clearance around the cable bundle during assembly planning.

Part Context

This component belongs to the WE-TOF series of ferrite cores manufactured by Würth Elektronik. The series focuses on providing versatile EMI suppression solutions through cylindrical designs that accommodate various cable diameters.
