7427022

Overview

The Würth Elektronik 7427022 is a split-core EMI suppression ferrite ring from the WE-SPLITRING series. It features an inner diameter of 11 mm and provides an impedance of 112 ohms at 100 MHz. Constructed with a hinged design requiring a key, it allows for installation around existing cables without disconnection. The component operates within a temperature range of -40°C to +125°C and is manufactured using 8W5000 material.

Feature Summary

• Split core design enables post-assembly installation on existing wiring harnesses
• Hinged mechanism ensures secure closure and consistent magnetic coupling
• High impedance performance effectively attenuates high-frequency electromagnetic interference

Applications

• Power supply output filtering
• Battery charger cable protection
• Portable electronic device EMI suppression

Procurement Notes

Verify part authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Check for recent Product Change Notices regarding material or dimensional updates. Ensure storage conditions maintain hinge integrity prior to installation.

Selection Notes

Select this component when retrofitting EMI suppression onto pre-assembled cables is required. The 11 mm inner diameter accommodates specific cable gauges. Choose based on the 112 ohm impedance requirement at target noise frequencies. Consider thermal limits for high-temperature environments.

Part Context

This component belongs to the WE-SPLITRING family of split ferrite cores. It complements solid core variants by offering flexible installation options. The series is designed for efficient power conversion and voltage regulation applications in compact electronic systems.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative split-core ferrites with matching 11 mm inner diameter and comparable impedance characteristics if availability is critical.
