Common Mode Chokes Procurement Notes

Verify the exact part number spelling as sources vary between ELF-25F025A and ELF25F025A. Confirm availability status as multiple distributors list this item as obsolete or out of stock. Ensure the required 2.5 A rating and 1.3 mH inductance match the specific circuit design requirements before ordering.

Common Mode Chokes Selection Notes

Select this component for applications requiring common mode noise suppression in single-phase AC lines. The 2.5 A current rating suits low-power consumer electronics. Verify that the physical footprint of 28x25x15 mm fits the PCB layout constraints. Ensure the through-hole pin spacing matches the recommended piercing plan.

Common Mode Chokes Part Context

This component belongs to the Panasonic F Series Type 25F line filters. It is categorized under analog mixed-signal IC filters and common mode chokes. The series includes variants with different inductance values but shares similar physical mounting characteristics.
