Procurement Notes
Verify the specific datasheet version to confirm impedance characteristics and thermal ratings. Ensure the through-hole footprint matches the target PCB layout dimensions. Confirm RoHS compliance status if required by the end product specifications. Check for any recent engineering change notices that may affect mechanical or electrical parameters before finalizing procurement.
Selection Notes
Select this component when high current capacity is required alongside effective common mode noise reduction. The low DC resistance minimizes power loss in the signal path. Consider the unshielded design regarding proximity to other sensitive components. Verify that the operating temperature range meets the environmental requirements of the intended application site.
Part Context
This component belongs to the TRACO Power filter component portfolio, specifically categorized under common mode chokes. It serves as a passive electromagnetic interference suppression device. The manufacturer specializes in power conversion solutions, and this part supports their broader ecosystem of electronic protection components.
Replacement Considerations
Consult official substitution lists for verified alternatives. Ensure replacement parts match the 45 µH inductance tolerance and 31.4 A current rating. Verify dimensional compatibility for through-hole mounting.
