744824407

Overview

The Würth Elektronik 744824407 is a WE-CMB series common mode power line choke designed for through-hole mounting. It features an inductance of 7 mH at 10 kHz and supports a maximum DC current rating of 3.5 A. The component has a maximum DC resistance of 80 mOhm. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides common mode noise suppression for power lines
• Designed for through-hole installation on printed circuit boards
• Constructed with shielded magnetic core technology

Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• Industrial equipment power line protection

Procurement Notes

Verify the specific package dimensions and lead time requirements against your assembly schedule before ordering. Confirm that the 3.5 A current rating meets the peak load demands of the target application. Ensure compatibility with automated through-hole placement equipment if applicable.

Selection Notes

Select this component when high inductance values are required for effective low-frequency noise attenuation. The 7 mH value is suitable for applications demanding significant common mode interference reduction. Consider the 80 mOhm DCR impact on overall system efficiency during normal operation.
