7427027

Overview

The Wurth Elektronik part number 7427027 is a split-core ferrite ring core belonging to the WE-SPLITRING series. It features an internal diameter of 14.5 mm and consists of two halves for easy installation around existing cables. The component utilizes 4W620 material, providing an impedance of 97 ohms at 100 MHz and 38 ohms at 25 MHz with one turn. Its external dimensions are 40 mm in width, 30 mm in height, and 20 mm in depth. The unit is compliant with RoHS and REACH standards.

Feature Summary

• Split design allows installation on pre-existing cables without disconnection
• Utilizes 4W620 material for effective electromagnetic interference suppression
• Includes integrated locking mechanism for secure assembly

Applications

• Electromagnetic interference suppression in general electronic equipment
• Power cable noise reduction
• Computer data line filtering

Procurement Notes

Verify that the specific order matches the manufacturer part number 7427027 exactly. Confirm the material composition is 4W620 and check compliance documentation for RoHS and REACH requirements. Ensure the internal diameter of 14.5 mm accommodates the target cable size. Review datasheet restrictions regarding usage in automotive or medical applications if applicable.

Selection Notes

Select this component when retrofitting EMI suppression onto installed wiring harnesses. The split-core architecture eliminates the need to disconnect cables during installation. Choose based on required impedance values at specific frequencies, specifically 97 ohms at 100 MHz. Ensure the physical aperture fits the cable bundle diameter comfortably while maintaining magnetic circuit integrity.

Part Context
