Procurement Notes
Verify the specific part number suffix against official Abracon documentation to confirm electrical characteristics such as inductance and current rating. Ensure the selected variant matches the required thermal operating range and physical dimensions for the target PCB layout. Cross-reference datasheet parameters with design specifications before finalizing procurement orders.
Selection Notes
Select this component based on its 2.7 mH inductance and 1.3 A current handling capability. Verify that the 680 mOhm DC resistance aligns with system efficiency requirements. Confirm the vertical package dimensions fit the available board space and that the through-hole pitch matches the PCB footprint design.
Part Context
This component belongs to the ALFT series of common mode chokes manufactured by Abracon LLC. The series offers various inductance and current ratings tailored for different power line filtering needs. The ALFT-03A-10 specifically targets applications requiring moderate inductance with higher current capacity compared to lower-rated variants in the same form factor.
Replacement Considerations
Consult official Abracon documentation for verified substitute part numbers within the ALFT series or equivalent products from other manufacturers. Ensure any replacement maintains identical inductance, current rating, and physical dimensions to guarantee compatibility.
