744834407

Overview

The Würth Elektronik 744834407 is a horizontal power line common mode choke from the WE-CMBH series. It features an inductance of 2x7 mH at 10 kHz and supports a maximum DC current of 3.5 A. The component has a maximum DC resistance of 80 mOhm per winding. Designed for through-hole mounting, it utilizes a toroidal core structure to provide effective electromagnetic interference suppression in power line applications.

Feature Summary

• Horizontal power line configuration for efficient PCB layout
• Toroidal core construction for high magnetic shielding
• Common mode noise suppression capability

Applications

• Power line filtering
• Electromagnetic interference suppression
• AC/DC converter input stages

Procurement Notes

Verify the specific datasheet version for the 744834407 to confirm mechanical dimensions and thermal ratings. Ensure the selected component matches the required 3.5 A current rating and 2x7 mH inductance specifications for your circuit design. Cross-reference the through-hole package style with your assembly process requirements.

Selection Notes

Select this component when horizontal mounting is preferred for space-constrained power line applications. The 3.5 A rating suits moderate power levels, while the 80 mOhm DCR minimizes voltage drop. Consider the toroidal shape for superior noise cancellation compared to planar alternatives in sensitive environments.

Part Context
