7446923010

Overview

The Würth Elektronik 7446923010 is a through-hole common mode choke belonging to the WE-LF Type XH series. It features two lines with an inductance of 10 mH per line and a maximum DC current rating of 3 A. The component has a maximum DC resistance of 0.155 Ω per line. It operates within a temperature range of -40°C to +125°C. Physical dimensions are 33.5 mm diameter by 20 mm height.

Feature Summary

• Dual-line configuration for common mode noise suppression
• Through-hole mounting for robust mechanical attachment
• High current handling capability suitable for power applications

Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• Noise reduction in industrial control systems

Procurement Notes

Verify the specific package type, as some sources indicate tray packaging while others suggest bulk or reel options depending on the distributor. Confirm the exact lead time and minimum order quantities directly with authorized suppliers before placing orders. Ensure compliance with RoHS and REACH standards required for your region.

Selection Notes

Select this component when high current capacity and low DC resistance are critical for power line filtering. The through-hole design offers better mechanical stability compared to surface mount alternatives in high-vibration environments. Consider the physical size constraints due to its cylindrical form factor.

Part Context

This part is part of Würth Elektronik's WE-LF Type XH series, designed for general-purpose EMI filtering. It complements other components in power electronics designs where common mode interference needs to be attenuated effectively without introducing significant voltage drop.

Replacement Considerations

Check for equivalent parts from Würth such as other WE-LF variants with similar inductance and current ratings. Verify that any substitute matches the 10 mH inductance, 3 A current rating, and 0.155 Ω DCR specifications to ensure circuit compatibility.
