Procurement Notes
Verify the specific part number ACM4520-421-2P-T000 against official TDK documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with required operating temperatures and current ratings before procurement. Cross-reference manufacturer datasheets for accurate handling and mounting specifications.
Selection Notes
Select this component when a 1.1 uH inductance and 420 Ohm impedance are required for common mode noise reduction. Consider the 2.4 A current rating and 55 mOhm resistance for power efficiency. The 1808 package size suits space-constrained designs requiring robust EMI suppression on power lines.
Part Context
This component belongs to the TDK ACM series of common mode chokes. It is categorized under EMC components and falls within the broader class of inductors, chokes, and coils. The ACM4520V series represents a specific variant within this family, sharing similar form factors but potentially differing in electrical characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative components by matching inductance, impedance, current rating, and package dimensions.
