744841210

Overview

The Würth Elektronik 744841210 is a through-hole common mode choke from the WE-CMB series. It features an inductance of 100 µH at 10 kHz with a tolerance of ±30%. The component supports a maximum DC current of 1.5 A and has a maximum DC resistance of 80 mΩ. It utilizes NiZn ferrite core material and offers high interference suppression with low capacitance winding techniques.

Feature Summary

• Broadband screening capability achieved through low capacitance winding techniques
• Compact design enabling highest possible current handling within small physical dimensions
• High interference compression for effective noise reduction

Applications

• Power line filtering in electronic circuits
• Common mode noise suppression in signal lines
• EMI mitigation in power supply inputs

Procurement Notes

Verify the specific package type and pin configuration against the official datasheet before integration, as through-hole components require distinct footprint considerations compared to surface-mount variants. Confirm that the 1.5 A current rating aligns with the thermal management capabilities of the target PCB layout to ensure reliable operation under continuous load conditions.

Selection Notes

Select this component when broadband noise suppression is required alongside high current capacity in a compact form factor. The NiZn core material provides suitable performance for general EMI filtering applications. Ensure the through-hole mounting style matches the assembly process and mechanical constraints of the final enclosure design.

Part Context

This part belongs to the WE-CMB series of common mode chokes manufactured by Würth Elektronik. The series is characterized by its use of NiZn ferrite cores and focus on providing high current handling in compact packages. The 744841210 specifically represents a 100 µH variant designed for through-hole implementation.

Replacement Considerations

Check for direct substitutes within the WE-CMB series with matching inductance and current ratings. Verify that any alternative component maintains the same through-hole pinout and physical dimensions to ensure compatibility with existing PCB footprints without redesign.
