74270051

Overview

The Würth Elektronik 74270051 is a cylindrical axial ferrite bead from the WE-AFB series, designed for EMI suppression. It features an internal diameter of 10.5 mm and an outer diameter of 15.5 mm, with a total length of 28 mm. The component utilizes 4W620 material to provide an impedance of 205 Ω at 100 MHz and 90 Ω at 25 MHz. It operates within a temperature range of -25°C to +105°C and complies with RoHS and REACH standards.

Feature Summary

• Cylindrical axial geometry for direct cable integration
• High impedance performance using 4W620 material composition
• Compliance with environmental directives including RoHS and REACH

Applications

• Electromagnetic interference suppression on cables
• RFI noise reduction in electronic assemblies
• Signal integrity enhancement for data lines

Procurement Notes

Verify the specific impedance tolerance and material batch consistency against the official datasheet before integration. Confirm that the axial dimensions match the physical clearance constraints of the target enclosure. Ensure the operating temperature range aligns with the environmental conditions of the final application to maintain performance stability.

Selection Notes

Select this component when a cylindrical form factor is required for axial cable mounting rather than snap-on rings. The 10.5 mm inner diameter accommodates specific cable gauges without excessive strain. Choose based on the required 205 Ω impedance at 100 MHz for effective high-frequency noise attenuation in sensitive circuits.

Part Context

This part belongs to the WE-AFB series of axial ferrite beads manufactured by Würth Elektronik. These components are distinct from split-core or snap-on types, offering a solid cylindrical structure for permanent installation on wires. The series focuses on providing reliable EMI/RFI suppression through standardized dimensional profiles and consistent magnetic material properties.
