Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct inductance and current ratings. Confirm package orientation and pinout specifications match design requirements. Check RoHS compliance status if required by project regulations. Validate datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this component based on the specific 2.5A current rating and required inductance level for noise suppression. Ensure the horizontal mounting style fits within the available board space constraints. Consider the thermal performance implications of the 200mOhm DC resistance at maximum operating currents. Verify that the physical dimensions align with the assembly process capabilities and automated placement equipment specifications.
