7427015

Overview

The Würth Elektronik 7427015 is a cylindrical ferrite core designed for electromagnetic interference (EMI) suppression. It belongs to the WE-TOF series and utilizes Nickel-Zinc (NiZn) material composition. The component features an inner diameter of 27.4 mm, an outer diameter of 40.6 mm, and a length of 15 mm. It provides an impedance of 54 Ohms at 25 MHz and 108 Ohms at higher frequencies within its operational range.

Feature Summary

• Cylindrical solid ferrite construction for cable wrapping
• Nickel-Zinc material composition for high-frequency noise attenuation
• Designed for EMI suppression on cables and wires

Applications

• Electromagnetic interface noise suppression
• Cable and wire EMI filtering
• General-purpose electromagnetic interference reduction

Procurement Notes

Verify the specific impedance requirements against application frequency ranges, noting the 54 Ohm rating at 25 MHz. Confirm physical dimensions match the target cable bundle size, specifically the 27.4 mm inner diameter. Ensure compliance with RoHS and REACH standards if required by the end product regulations. Cross-reference the WE-TOF series datasheet for detailed thermal characteristics.

Selection Notes

Select this component when a solid toroidal shape is preferred over split cores for permanent cable installations. The Nickel-Zinc material offers superior performance at higher frequencies compared to Manganese-Zinc alternatives. Consider the 15 mm length and 40.6 mm outer diameter for spatial constraints in the assembly design. This part is suitable for applications requiring robust, non-opening ferrite solutions.

Part Context

This component is part of the WE-TOF series from Würth Elektronik, which specializes in toroidal ferrite cores for EMI suppression. The series includes various sizes and materials to address different frequency and current requirements. The 7427015 specifically targets applications needing a solid, durable core that can be installed around existing cabling without disconnection.

Replacement Considerations

Direct substitutes include other Würth Elektronik WE-TOF series parts with similar dimensions and NiZn composition. Verify impedance curves and material grades when considering cross-brand alternatives to ensure equivalent high-frequency attenuation performance.
