Procurement Notes

Verify the specific suffix against official Wurth documentation to confirm exact electrical tolerances and packaging details. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the datasheet revision date with your production timeline to avoid obsolescence risks during sourcing.

Selection Notes

Select this component when a through-hole solution is required for high-current common mode noise reduction. The 10 mH value suits lower frequency interference. Verify that the 0.7 A rating meets the circuit's continuous current requirements without saturation. Consider thermal derating if operating near the upper temperature limit.

Part Context

This part belongs to the WE-FC series, which focuses on current-compensated chokes for power lines. These components are engineered to handle differential currents while attenuating common mode signals. The series is widely used in environments requiring strict electromagnetic compatibility standards.

Replacement Considerations

Check for direct substitutes within the WE-FC series with matching 10 mH inductance and similar current ratings. Ensure any replacement maintains the through-hole package dimensions and AEC-Q200 qualification status for automotive applications.
