Procurement Notes
Verify the complete part number against official TDK documentation to ensure correct inductance and current ratings. Confirm package dimensions and mounting requirements match your PCB layout specifications. Check for RoHS compliance status and specific safety certifications required for your target market before finalizing procurement orders.
Selection Notes
Select this component when high current handling capability above 24A is required alongside low DC resistance. Ensure the application voltage does not exceed 250VAC. Consider the physical footprint constraints as the maximum length is 40.00mm. Validate thermal performance under continuous load conditions to maintain reliability in industrial or automotive environments.
Part Context
This component belongs to the TDK SurfIND SMD High-Current Chokes series. The series is engineered for demanding applications where space efficiency and high current capacity are critical. TDK Electronics provides these components to support robust electronic system designs across various technology sectors.
Replacement Considerations
Consult official TDK substitution guides for compatible alternatives. Verify that any substitute maintains identical inductance, current rating, and physical dimensions to ensure seamless integration without redesigning the printed circuit board.
