7427011

Overview

The Würth Elektronik 7427011 is a WE-TOF series toroidal ferrite core designed for EMI suppression. It features a square cross-section with an inner diameter of 8 mm, outer diameter of 16.5 mm, and length of 16 mm. The component provides an impedance of 148 ohms at 100 MHz. Constructed from high-permeability ferrite material, it supports cable diameters up to the specified inner dimension. This snap-on style core facilitates rapid installation on cables without requiring disconnection.

Feature Summary

• Snap-on design enables quick installation directly onto existing cables
• Toroidal geometry ensures effective magnetic flux containment
• High permeability material optimizes noise attenuation performance

Applications

• EMI suppression on data communication lines
• Noise reduction on power supply cables
• Signal integrity enhancement in industrial control systems

Procurement Notes

Verify the specific impedance value and frequency characteristics against the official datasheet before integration. Confirm that the target cable diameter falls within the 8 mm inner diameter specification to ensure proper fit. Check RoHS compliance status via manufacturer documentation. Ensure the selected part number matches the required physical dimensions for the assembly.

Selection Notes

Select this component when a snap-on solution is preferred over split-core designs for permanent installations. Consider the 148 ohm impedance rating relative to the noise frequencies present in the application. Evaluate the physical space constraints against the 16.5 mm outer diameter. Compare against other WE-TOF variants if different impedance or size requirements exist.

Part Context

This component belongs to the WE-TOF series of toroidal ferrite cores manufactured by Würth Elektronik. The series offers various impedance ratings and physical sizes tailored for diverse EMI suppression needs. The 7427011 specifically targets applications requiring moderate impedance with a compact form factor suitable for standard cable sizes.

Replacement Considerations

Consult the official Wurth Elektronik catalog for alternative part numbers within the WE-TOF series that offer different impedance values or dimensions. Verify mechanical compatibility and electrical performance equivalence before substituting.
