- Power supply input stages
Procurement Notes
Verify the complete part number including suffixes to ensure correct inductance and current ratings. Confirm package type and pin configuration match the target PCB footprint. Check RoHS compliance status if required by specific regulatory frameworks. Ensure storage conditions align with moisture sensitivity level requirements before assembly.
Selection Notes
Select this component when a 3.3 mH inductance at 10 kHz is required for common mode noise reduction. Ensure the circuit current does not exceed 1.5 A to prevent saturation or excessive heating. Verify that the through-hole package fits the available board space. Consider the DCR value for potential power loss calculations in the design phase.
Part Context
This part belongs to the C201021A series from ITG Electronics, Inc., which specializes in magnetic components and EMI filters. The series includes various inductance values tailored for different filtering needs. ITG Electronics focuses on designing robust magnetic modules for industrial and commercial applications.
Replacement Considerations
Direct substitutes must match the 3.3 mH inductance, 1.5 A current rating, and through-hole package. Verify equivalent DCR and frequency response characteristics. Cross-reference with other manufacturers offering similar two-line common mode chokes if availability is constrained.
