74270022

Overview

The Würth Elektronik 74270022 is a solid ferrite cable core belonging to the WE-SAFB series, designed for electromagnetic interference suppression. It features a round physical shape with an outer diameter of 6 mm and a height of 10 mm. The component provides an impedance of 35 Ohms at a test frequency of 25 MHz for a single turn configuration. It operates within a temperature range of -25°C to 105°C and is suitable for cables up to 3.45 mm in diameter.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics at specific frequencies.
• Features a solid construction designed for easy installation onto existing cable assemblies.
• Supports single-turn application configurations for targeted noise reduction.

Applications

• Electromagnetic interface noise suppression
• Cable assembly EMI filtering
• General-purpose electromagnetic interference mitigation

Procurement Notes

Verify the specific impedance value against the required frequency spectrum for your application, as ferrite performance varies significantly with frequency. Confirm that the inner diameter accommodates the target cable diameter without excessive force or looseness. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when a snap-on or slide-on ferrite solution is preferred over molded beads for post-assembly modification. Consider the impedance curve at the specific noise frequency rather than just the rated value. Evaluate the mechanical fit for the cable bundle size to ensure secure retention during vibration or handling.

Part Context

This part belongs to the WE-SAFB series of shielded ferrite cable cores from Würth Elektronik. These components are engineered for rapid prototyping and production line integration where flexible EMI suppression on finished cables is required. The series offers various impedance values and dimensions to suit different cable sizes and noise profiles.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Engineers should verify compatibility with alternative suppliers by matching impedance curves, physical dimensions, and material composition carefully.

FAQ

What is the maximum cable diameter supported by the 74270022?

The component is designed for cables with a diameter up to 3.45 mm.

How does the impedance change with multiple turns?

The specified impedance of 35 Ohms is for a single turn. Impedance generally increases with additional turns, but specific multi-turn data should be verified from the official datasheet.
