Overview

The Würth Elektronik 7446120027 is a current-compensated common mode choke from the WE-LF Type SV series. It features an inductance of 27 mH and a DC resistance of 1.2 ohms. The component supports a maximum DC current of 400 mA and operates within a temperature range up to 125°C.

Feature Summary

Current-compensated design for power line applications
Common mode filtering capability
Surface mount construction

Applications

Power line filtering
EMI suppression in electronic circuits

Procurement Notes

Verify the specific suffix 'SV' against official Wurth documentation to confirm exact electrical tolerances and physical dimensions. Ensure compatibility with surface mount assembly processes and check for RoHS compliance status in the latest datasheet revision before finalizing procurement.

Selection Notes

Select this component when a high inductance value of 27 mH is required for common mode noise reduction in low-current power lines. The 400 mA rating suits applications where current compensation is beneficial. Verify that the 1.2 ohm DC resistance fits the circuit's voltage drop constraints.

Part Context

This part belongs to the WE-LF series, which focuses on low-frequency common mode chokes. The Type SV designation indicates specific construction characteristics within this family. It serves as a passive component for electromagnetic interference mitigation in power supply inputs.

Replacement Considerations

Consult official Wurth Elektronik substitution guides for verified alternatives. Cross-reference inductance, current rating, and package dimensions with other WE-LF variants if sourcing constraints exist.
