7427028

Overview

The Würth Elektronik part number 7427028 is a split core ferrite component belonging to the WE-SPLITRING series. It features an internal diameter of 26.5 mm and provides an impedance of 200 ohms at 100 MHz. Designed for rapid installation, this snap-on magnetic ring allows engineers to add EMI suppression to existing cables without disconnecting them. The unit utilizes high-performance ferrite material to attenuate high-frequency noise across power and data lines.

Feature Summary

• Snap-on split core design enables installation on terminated cables without disconnection
• Provides significant electromagnetic interference attenuation in high-frequency ranges
• Utilizes specialized ferrite material optimized for broadband noise suppression

Applications

• Suppression of electromagnetic interference on existing power cables
• Noise reduction on data transmission lines in digital equipment
• EMI mitigation on coaxial cables within electronic assemblies

Procurement Notes

Verify the specific impedance value and frequency rating against your system requirements before ordering. Confirm that the cable diameter fits within the 26.5 mm aperture. Ensure the ferrite material composition aligns with your target noise spectrum. Check for RoHS compliance if required by your manufacturing standards. Validate the split mechanism integrity for repeated opening and closing cycles.

Selection Notes

Select this component when retrofitting EMI protection onto installed cabling is necessary. The split core architecture offers convenience over traditional toroidal rings that require wire threading. Choose based on the required impedance magnitude at your operating frequency. Ensure the physical dimensions accommodate the cable bundle size. Consider the material properties for the specific frequency band of interference.

Part Context

This component is part of Würth Elektronik's WE-SPLITRING series, which specializes in easy-installation ferrite solutions. The series addresses the need for post-assembly noise filtering in complex electronic systems. These components bridge the gap between fixed magnetic cores and flexible cable management needs.
