7427114

Overview

The Würth Elektronik 7427114 is a snap-on ferrite core sleeve designed for cable and wire noise suppression. It features a hinged design with a plastic case, allowing for easy installation around existing cables without disconnection. The component utilizes 3W800 material to provide an impedance of 144 Ohms at 100 MHz. It has a circular shape with a free-hanging installation type. The internal diameter is 5.00 mm (0.197 inches), accommodating standard cable sizes. External dimensions are approximately 16 mm width, 13 mm height, and 25.8 mm length.

Feature Summary

• Hinged snap-on design enables rapid installation on pre-existing cables
• Integrated plastic case protects the ferrite material and provides structural integrity
• High impedance performance at 100 MHz for effective EMI/RFI noise attenuation

Applications

• Suppression of electromagnetic interference on data cables
• Noise reduction on power supply lines in electronic equipment
• EMI mitigation in automotive wiring harnesses

Procurement Notes

Verify the specific material grade (3W800) and impedance characteristics against your frequency requirements. Confirm that the internal diameter of 5.00 mm accommodates the target cable bundle size. Ensure the hinged mechanism is suitable for the intended environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this part when non-invasive installation is required for cable noise suppression. The snap-on mechanism distinguishes it from split cores that require separate keys or tools. Consider the external dimensions to ensure adequate clearance within the assembly. Compare impedance values at relevant frequencies against alternative materials like 4W620 if higher frequency performance is needed.

Part Context

This component belongs to the STAR-TEC series of ferrite cores from Würth Elektronik. The series offers various sizes and materials to address different EMI suppression needs. The 7427114 specifically targets applications requiring quick deployment on cables up to 5 mm in diameter. It complements other accessories such as safety keys and kits available in the same product family.

Replacement Considerations

Direct substitutes include other snap-on ferrites with similar 5 mm ID and comparable impedance. Verify material composition differences, as alternatives may use 4W800 or other grades affecting high-frequency performance. Ensure mechanical fitment matches the housing constraints. Cross-reference with distributor databases for equivalent part numbers from other manufacturers.
