7446622001

Overview

The Würth Elektronik 7446622001 is a current-compensated common mode choke from the WE-LF Type SH series. It features a 1 mH inductance at 10 kHz and supports a DC current rating of 2 A with a maximum DC resistance of 0.06 Ohms. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Current-compensated design for efficient power line filtering
• Shielded construction to minimize electromagnetic interference
• Through-hole mounting configuration for robust mechanical stability

Applications

• Power supply input filtering
• DC-DC converter noise suppression
• Industrial control system EMI reduction

Procurement Notes

Verify the specific package type and lead times directly with authorized distributors, as availability may vary. Confirm that the 2A current rating meets your circuit requirements under all operating conditions. Ensure compatibility with your PCB layout for through-hole assembly processes.

Selection Notes

Select this component when high current handling capability is required alongside effective common mode noise attenuation. The low DC resistance minimizes power loss in the signal path. Consider the physical size constraints for through-hole placement on the target printed circuit board.

Part Context

This part belongs to the WE-LF Type SH series, designed for shielding and high-performance applications. It complements other Wurth Elektronik passive components by providing reliable noise suppression in compact form factors suitable for modern electronic designs requiring strict EMC compliance.

Replacement Considerations

Check datasheets for equivalent inductance and current ratings. Verify pinout compatibility if substituting in existing layouts. Ensure thermal performance matches the original design specifications.
