74270010

Overview

The Wurth Elektronik part number 74270010 is a cylindrical ferrite core belonging to the WE-SAFB series. It is designed for EMI suppression on cables with a 1 mm inner diameter. The component exhibits an impedance of 55 ohms at 25 MHz and features a length of 4.5 mm, an outer diameter of 3.5 mm, and an inner diameter of 1.2 mm.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies.
• Features a solid cylindrical design suitable for direct cable installation without opening mechanisms.

Applications

• EMI suppression for small gauge signal or power cables
• High-frequency noise filtering in compact electronic assemblies

Procurement Notes

Verify the exact impedance value and frequency specification against the official manufacturer datasheet before integration. Confirm that the 1.2 mm inner diameter accommodates the target cable insulation thickness. Ensure compliance with RoHS requirements if mandated by the end-product regulations.

Selection Notes

Select this component when space constraints require a low-profile cylindrical core rather than split-ring types. The 55 ohm impedance at 25 MHz indicates suitability for mid-range frequency noise attenuation. Verify cable fitment strictly due to the narrow 1.2 mm bore size.

Part Context

This component is part of the WE-SAFB series from Wurth Elektronik, which specializes in solid ferrite cores for cable applications. Unlike snap-open variants, these are fixed cylinders intended for permanent installation on wires during manufacturing or assembly processes.

Replacement Considerations

No public substitute part numbers are documented for this specific model. Cross-referencing requires matching the 55 ohm @ 25 MHz impedance, 1.2 mm ID, and 4.5 mm length specifications precisely.
