74270011

Overview

The Würth Elektronik part number 74270011 is a cylindrical ferrite core belonging to the WE-SAFB series, designed for EMI suppression. It features an inner diameter of 1.6 mm and an outer diameter of 4.1 mm, with a total length of 3.2 mm. The component exhibits an impedance of 28 Ohms at 25 MHz. Constructed as a small-size bead, it serves as a passive filter element for high-frequency noise attenuation on cables and traces.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics
• Compact cylindrical geometry suitable for space-constrained applications
• Designed for direct integration onto wires or PCB traces

Applications

• High-speed data line filtering
• Power cable noise suppression
• General EMI mitigation in compact electronic assemblies

Procurement Notes

Verify the specific impedance tolerance and material composition against the official Wurth Elektronik datasheet before finalizing procurement. Confirm that the 1.6 mm inner diameter accommodates the target conductor size without mechanical stress. Ensure compliance with relevant environmental directives such as RoHS if required by the end product specifications.

Selection Notes

Select this component when a low-profile, cylindrical ferrite bead is required for frequencies around 25 MHz. The 4.1 mm outer diameter provides sufficient magnetic mass for moderate noise suppression while maintaining a minimal footprint. Consider the 3.2 mm length for spatial constraints where larger snap-on cores cannot fit.

Part Context

This component is part of the WE-SAFB series from Würth Elektronik, which specializes in small-size EMI suppression solutions. The series targets applications requiring effective noise reduction in limited spaces, offering a balance between physical dimensions and electromagnetic performance for modern compact electronics.
