7427727

Overview

The Würth Elektronik part number 7427727 identifies a WE-AFB LFS axial ferrite bead designed for EMI suppression. This component utilizes a solid ferrite core material to provide impedance against electromagnetic interference in electronic circuits. The device features an internal diameter of 6.1 mm, accommodating specific wire gauges. It exhibits an impedance value of 100 ohms at 100 MHz. The construction supports operation within a temperature range of -55°C to +125°C. Compliance with RoHS standards ensures suitability for modern environmental regulations.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics
• Features a solid axial design suitable for direct integration into wiring harnesses
• Operates reliably across extended industrial temperature ranges

Applications

• General electronic equipment signal line filtering
• Power supply cable noise reduction
• Data communication interface protection

Procurement Notes

Verify the specific impedance curve and frequency response requirements against application needs before procurement. Confirm that the 6.1 mm inner diameter matches the target conductor size. Ensure compliance with RoHS directives is required for the specific project. Check datasheet for thermal derating information if operating near maximum temperature limits.

Selection Notes

Select this component when axial ferrite beads are preferred over snap-on cores for permanent installations. Consider the 100 ohm impedance at 100 MHz as the primary noise attenuation metric. Evaluate space constraints as axial components require linear mounting space. Compare with other WE-AFB series variants if different impedance profiles or physical dimensions are necessary for the layout.

Part Context

This part belongs to the WE-AFB LFS series from Würth Elektronik, focusing on low-frequency suppression applications. The LFS designation indicates specific material properties optimized for general EMI reduction. It complements the company's broader portfolio of magnetic components, offering a standardized solution for common noise filtering tasks in consumer and industrial electronics.

Replacement Considerations

Cross-reference with other Wurth WE-AFB series parts for similar impedance values. Verify compatibility with alternative manufacturers' axial ferrite beads by matching inner diameter and impedance curves. Ensure substitute parts meet the same RoHS compliance and temperature rating specifications.
