74270020

Overview

The Würth Elektronik 74270020 is a solid cylindrical ferrite cable core from the WE-SAFB series, designed for electromagnetic interference suppression. It features an inner diameter of 2.4 mm and an outer diameter of 7.5 mm, with a length of 7.5 mm. Constructed from 3W800 material, it provides an impedance of 103 Ohms at 25 MHz and 108 Ohms at 100 MHz. The component operates within a temperature range of -25°C to +125°C and complies with RoHS and REACH standards.

Feature Summary

• Solid cylindrical design for easy installation onto round cables
• High-frequency noise suppression using 3W800 ferrite material
• Compliant with RoHS and REACH environmental directives

Applications

• Electromagnetic interference suppression in electronic circuits
• Filtering high-frequency noise on power and signal cables
• General EMI mitigation for round cable assemblies

Procurement Notes

Verify the specific impedance requirements against application frequency needs, as values are specified at 25 MHz and 100 MHz. Confirm that the cable diameter fits within the 2.4 mm inner diameter tolerance. Ensure compliance with RoHS and REACH regulations is required for the target market. Check operating temperature limits to ensure suitability for the intended environment.

Selection Notes

Select this component when a solid, non-split ferrite core is preferred over snap-on types for permanent cable treatment. The 2.4 mm bore size dictates compatibility with smaller gauge wires. Consider the 3W800 material properties for the specific frequency spectrum of interference being addressed. Evaluate space constraints given the 7.5 mm length and 7.5 mm outer diameter dimensions.

Part Context

This part belongs to the WE-SAFB series of solid ferrite cable cores manufactured by Würth Elektronik. These components are distinct from split-core or bead types, offering a robust solution for fixed cable installations. The series focuses on providing reliable EMI suppression through standardized cylindrical geometries and specific ferrite material compositions optimized for broadband noise attenuation.
