7427247

Overview

The Würth Elektronik 7427247 is a snap-on ferrite core from the STAR-FLAT series, designed for electromagnetic interference suppression. It features a flat geometry with a grey 4W620 material composition and Safety Key technology. The component has an inner diameter of 19.2 mm and external dimensions of 63.5 mm in length, 31.8 mm in width, and 12.7 mm in height. It provides an impedance of 72 Ohms at 25 MHz and 192 Ohms at 100 MHz. The operating temperature range spans from -25°C to +105°C.

Feature Summary

• Snap-on design with Safety Key locking mechanism for secure installation
• Flat rectangular geometry optimized for cable bundles
• Grey 4W620 ferrite material composition

Applications

• Electromagnetic compatibility enhancement for cables
• Suppression of common mode noise in electronic assemblies
• General EMI filtering applications

Procurement Notes

Verify the specific impedance value required for your frequency band, as datasheets may list 72 Ohms at 25 MHz or 192 Ohms at 100 MHz depending on the test condition. Confirm the inner diameter matches the target cable size. Ensure compliance with RoHS and REACH standards if required by your region. Check the latest datasheet for any updates to the Safety Key specifications.

Selection Notes

Select this part when a flat profile is necessary to fit within constrained spaces around cable bundles. The 19.2 mm inner diameter accommodates thicker cables or multiple wires. The 4W620 material offers high permeability for effective low-frequency noise suppression. Consider the operating temperature range of -25°C to +105°C for environmental suitability.

Part Context
