74270017

Overview

The Würth Elektronik 74270017 is a WE-SAFB series axial EMI suppression ferrite bead designed for high-frequency noise attenuation. Constructed from 4W620 ferrite material, it provides an impedance of 145 Ω at 25 MHz. The component features a cylindrical geometry with an inner diameter of 1.58 mm and an outer diameter of 3.8 mm. It has a total length of 13.97 mm and weighs approximately 1.62 g. This part is suitable for general electronic equipment applications requiring compact signal integrity solutions.

Feature Summary

• Utilizes 4W620 ferrite material for effective high-frequency interference suppression
• Compact axial design facilitates easy integration into dense circuit layouts
• Provides specific impedance characteristics to attenuate common mode noise

Applications

• General electronic equipment noise suppression
• High-frequency signal line filtering
• Cable and wire EMI mitigation in consumer electronics

Procurement Notes

Verify the exact impedance tolerance and frequency response curve against the official 74270017 datasheet before implementation. Confirm that the 1.58 mm inner diameter accommodates the target conductor size without mechanical stress. Ensure compliance with RoHS standards if required by the end product specifications.

Selection Notes

Select this component when space constraints require a small form factor compared to snap-on cores. The 145 Ω impedance at 25 MHz makes it suitable for moderate frequency noise profiles. Consider the fixed axial shape for permanent installation rather than field-installable cable wrapping applications.

Part Context

This part belongs to the WE-SAFB series, which focuses on small-size EMI suppression ferrites. It complements larger snap-on cores like the STAR-TEC or STAR-RING series by offering a pre-formed solution for smaller wires. The series emphasizes ease of assembly and consistent performance across general electronic applications.
