7427729

Overview

The Wurth Elektronik 7427729 is an axial ferrite bead from the WE-AFB LFS series designed for EMI suppression. It features a cylindrical core with an inside diameter of 9.25 mm and an outside diameter of 19.5 mm. The component provides an impedance of 60 Ohms at a test frequency of 10 MHz. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance characteristics at specific frequencies
• Utilizes a low-profile axial design suitable for direct cable mounting without additional hardware
• Constructed with durable materials ensuring stable performance across wide industrial temperature ranges

Applications

• Suppression of common mode noise on power cables
• EMI reduction in computer data transmission lines
• Noise filtering on printed circuit board interconnects

Procurement Notes

Verify the part number against official Wurth Elektronik documentation to confirm specifications. Ensure compatibility with cable diameters up to 9.25 mm. Check for RoHS compliance requirements relevant to your region. Confirm operating temperature limits meet application needs. Validate impedance values at target frequencies using manufacturer datasheets.

Selection Notes

Select this component when axial ferrite beads are required for cables fitting within the 9.25 mm aperture. Consider the 60 Ohm impedance at 10 MHz for noise profiles in that spectrum. Evaluate thermal stability requirements against the -40°C to +125°C rating. Compare physical dimensions against available space constraints. Assess material compatibility with surrounding environments.
