744823220

Overview

The Würth Elektronik 744823220 is a WE-CMB series common mode power line choke designed for through-hole mounting. It features an inductance of 20 mH at 10 kHz with a maximum DC current rating of 1.5 A and a maximum DC resistance of 270 mΩ. The component utilizes a Type M core structure and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides effective common mode noise suppression for power lines
• Features a robust molded construction for mechanical stability
• Supports high current handling capabilities up to 1.5 A

Applications

• Power supply input filtering
• EMI suppression in consumer electronics
• Industrial control systems

Procurement Notes

Verify the specific package type and lead frame configuration against the official datasheet before integration. Confirm that the 270 mΩ DCR and 1.5 A current ratings align with the thermal management requirements of the target application design.

Selection Notes

Select this component when high inductance values are required for low-frequency noise attenuation in unshielded through-hole applications. Ensure the physical footprint accommodates the larger dimensions typical of the WE-CMB Type M series compared to surface mount alternatives.

Part Context

This part belongs to the Würth Elektronik WE-CMB family, which specializes in high-performance common mode chokes. The series offers various inductance and current combinations, with the 744823220 representing a higher inductance option suitable for stringent EMI compliance needs in power line environments.

Replacement Considerations

Cross-reference with other WE-CMB variants such as 744823210 or 744823230 for different inductance levels. Verify pin compatibility and thermal characteristics when substituting with generic equivalents.
