7427026

Overview

The Wurth Elektronik 7427026 is a split-core ferrite ring designed for electromagnetic interference suppression. It belongs to the WE-SPLITRING series and features a nickel-zinc material composition. The component provides an impedance of 98 ohms at 100 MHz, with a minimum operating frequency of 25 MHz. It has a cable diameter capacity of 10 mm and measures approximately 10 mm in width. The unit complies with RoHS standards and is suitable for EMI interface applications.

Feature Summary

• Split-core design enables installation on existing cables without disconnection
• Nickel-zinc ferrite material ensures effective high-frequency noise attenuation
• Provides defined impedance characteristics for targeted EMI suppression

Applications

• Electromagnetic interface noise reduction
• Cable harness EMI filtering
• Power supply line interference suppression

Procurement Notes

Verify the specific impedance value at 100 MHz matches system requirements. Confirm the 10 mm cable diameter accommodates the target wire gauge. Ensure compliance with RoHS directives for the intended market. Check datasheet specifications for temperature range limitations during operation.

Selection Notes

Select this model when non-invasive installation on pre-assembled cables is required. Choose based on the 98 ohm impedance profile for the relevant frequency band. Consider the 10 mm aperture size relative to the cable bundle dimensions. Evaluate the nickel-zinc material properties against competing ferrite compositions.

Part Context

This component is part of the WE-SPLITRING series from Wurth Elektronik. It serves as an accessory for electromagnetic compatibility improvements.
