742730223

Overview

The Würth Elektronik 742730223 is a WE-MLS Multiline EMI Suppression Ferrite Bead designed for power line applications. It features an impedance of 334 Ohms at 100 MHz and supports a current rating of 4 Amperes with a DC resistance of 2 milliohms. The component utilizes an 8-terminal through-hole (THD) package configuration, ensuring robust mechanical stability for industrial environments.

Feature Summary

• Provides effective electromagnetic interference suppression for multiline power lines
• Engineered for high-current handling capabilities in demanding electronic equipment
• Constructed with materials compliant with RoHS and REACH standards

Applications

• General electronic equipment power line filtering
• Industrial machinery noise reduction
• Consumer electronics power input stages

Procurement Notes

Verify the specific datasheet version to confirm terminal pinout and mounting hole dimensions. Ensure the selected variant matches the required 4A current rating and 334 Ohm impedance specifications for your circuit design. Cross-reference the package type to confirm compatibility with your PCB layout or cable assembly requirements before finalizing orders.

Selection Notes

Select this component when multiline EMI suppression is required for power lines carrying up to 4 Amperes. The 334 Ohm impedance at 100 MHz makes it suitable for broadband noise attenuation. Consider the through-hole mounting style if surface space is limited or higher mechanical retention is needed compared to SMD alternatives.

Part Context

This ferrite bead belongs to the WE-MLS series from Würth Elektronik, specialized for multiline applications. Unlike single-line beads, these components are designed to suppress common-mode noise across multiple conductors simultaneously, making them essential for maintaining signal integrity in complex power distribution systems within general electronic devices.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify electrical parameters such as impedance frequency response and current rating carefully when considering alternative manufacturers.
