74270024

Overview

The Wurth Elektronik 74270024 is a cylindrical solid ferrite cable core from the WE-SAFB series, designed for electromagnetic interference suppression. Constructed from NiZn material (4W620), it provides broadband attenuation across high-frequency ranges. The component features an inner diameter of 3.18 mm and an outer diameter of 7.6 mm, with a length of 10 mm. It exhibits an impedance of 72 Ohms at 25 MHz and 106 Ohms at 100 MHz. Operating within a temperature range of -25°C to +125°C, it complies with RoHS and REACH standards.

Feature Summary

• Broadband frequency operation utilizing NiZn ferrite material
• Compact cylindrical design for easy cable installation
• High-temperature stability suitable for demanding environments

Applications

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

Procurement Notes

Verify the specific impedance values against the official datasheet for your target frequency, as performance varies with frequency. Confirm that the inner diameter accommodates the cable bundle without excessive force. Ensure compliance requirements such as RoHS are explicitly stated in the final procurement documentation to match project specifications.

Selection Notes

Select this part when a small form factor is required for EMI filtering on thin cables. The 3.18 mm bore size limits usage to smaller gauge wires or multiple thin conductors. Consider the 10 mm length for space-constrained layouts where larger cores cannot fit. Evaluate the 72 Ohm impedance at 25 MHz to ensure sufficient attenuation for the specific noise frequencies present in the application.

Part Context

This component belongs to the WE-SAFB series of small-size EMI suppression ferrite beads. Unlike split-core variants, this solid cylindrical design offers consistent magnetic properties along its entire length. It serves as a passive component to dissipate high-frequency noise energy as heat, protecting sensitive circuits from electromagnetic disturbances.

Replacement Considerations
