7446321050

Overview

The Würth Elektronik 7446321050 is a through-hole common mode filter choke from the WE-LF Type LV series. It features an inductance of 50 mH at 10 kHz and supports two lines with a maximum DC current rating of 600 mA. The component has a maximum DC resistance of 1.2 Ohms and operates within a temperature range of -40°C to +125°C. It is designed for power line filtering applications requiring robust electromagnetic interference suppression.

Feature Summary

• Provides effective common mode noise attenuation for dual-line power circuits
• Utilizes a through-hole mounting style for secure PCB integration
• Constructed with high-permeability core material for stable inductance performance

Applications

• Power supply input filtering
• AC mains line noise suppression
• Electromagnetic interference (EMI) reduction in consumer electronics

Procurement Notes

Verify the specific package type and lead times directly with authorized distributors, as availability may vary. Confirm that the through-hole footprint matches your PCB design requirements before ordering. Ensure compliance with RoHS and REACH regulations if required by your manufacturing standards. Check for any recent product change notices that might affect mechanical dimensions or electrical characteristics.

Selection Notes

Select this component when high inductance values are needed for low-frequency common mode noise suppression. The 600 mA current rating suits moderate power applications. Consider the through-hole format if automated surface-mount assembly is not available or if higher mechanical stability is required. Compare DCR losses against thermal management capabilities in the final enclosure design.

Part Context

This part belongs to the WE-LF Type LV series, which focuses on low-frequency common mode chokes. These components are engineered for general-purpose power line filtering. The series offers various inductance values to suit different noise profiles while maintaining consistent physical footprints for design flexibility across multiple product generations.

Replacement Considerations

Direct substitutes must match the 50 mH inductance, 600 mA current rating, and 1.2 Ohm DCR. Verify that alternative parts support through-hole mounting and operate within the same temperature range. Cross-reference pin configurations and physical dimensions to ensure compatibility with existing PCB layouts without redesign.
