7427052

Overview

The Würth Elektronik 7427052 is a multi-aperture EMI suppression core designed for signal line filtering. It features an axial ferrite bead construction with an inner diameter of 8 mm, outer diameter of 16 mm, and height of 16 mm. The component utilizes 3W800 ferrite material to provide effective noise attenuation in the 25 MHz to 100 MHz frequency range. Electrical specifications include an impedance of 24 Ohms at 25 MHz (±25% tolerance) and 91 Ohms at 100 MHz for single-wire configurations, or 102 Ohms for double-wire setups.

Feature Summary

• Multi-aperture design facilitates efficient cable routing and secure clamping around conductors
• Utilizes 3W800 ferrite material optimized for high-frequency electromagnetic interference suppression
• Axial geometry supports installation on coaxial cables, twisted pairs, and multi-wire assemblies

Applications

• Electromagnetic interference suppression for coaxial cables
• Noise filtering for twisted pair wiring harnesses
• EMI mitigation for general electrical wires and multi-conductor cables

Procurement Notes

Verify that the specific order matches part number 7427052 to ensure correct 8 mm inner diameter and 3W800 material composition. Confirm compliance requirements against project specifications, noting the product is intended for general electronic equipment only. Check datasheet limitations regarding safety-critical applications where failure could cause severe injury. Ensure storage conditions remain within -20°C to +60°C prior to assembly to maintain material integrity.

Selection Notes

Select this component when targeting noise reduction in the 25 MHz to 100 MHz spectrum for cables fitting within an 8 mm aperture. The 3W800 material offers a balance of permeability and resistivity suitable for broadband suppression. Consider the multi-aperture structure for ease of installation on existing cabling without disconnection. Evaluate impedance requirements at 100 MHz to ensure sufficient attenuation for the specific noise profile encountered in the target application environment.
