Procurement Notes
Verify the specific part number ALFT-03A-8 against official Abracon documentation to confirm electrical parameters such as 5.5 mH inductance and 1 A current rating. Ensure compatibility with required thermal operating ranges and physical mounting dimensions before procurement. Cross-reference datasheets to validate pin configurations and insulation characteristics.
Selection Notes
Select this component when designing circuits requiring common mode chokes for AC line applications with moderate current handling needs. Consider the 1 A maximum DC current and 750 milliohm DCR limits during circuit design. Evaluate the physical footprint and through-hole mounting requirements against available PCB space and assembly processes.
Part Context
This component belongs to the Abracon ALFT series of common mode filters. The series includes various models with differing inductance values and current ratings, such as the ALFT-03A-9 and ALFT-03A-10. These components are engineered for general-purpose EMI suppression in consumer and industrial electronics.
Replacement Considerations
Consult official Abracon substitution guides or equivalent manufacturer catalogs for verified alternatives. Ensure any substitute matches the 5.5 mH inductance, 1 A current rating, and through-hole form factor.
