Fixed Inductors Procurement Notes
Verify the specific part number suffix against official Central Technologies documentation to confirm exact tolerance and compliance status. Ensure that the ordering specifications match the required inductance value and physical dimensions for the target PCB layout. Cross-reference the manufacturer's latest datasheet to confirm current availability and any potential obsolescence notices before finalizing procurement plans.
Fixed Inductors Selection Notes
Select this component when a shielded SMD inductor with a 22 µH nominal value is required. The 1808 footprint offers a balance between current handling capability and board space efficiency. Consider the ±20% tolerance for circuit design margins. Verify thermal performance requirements against the rated current specifications provided in the official datasheet to ensure stable operation under load conditions.
Fixed Inductors Part Context
This part belongs to the CTMMP series of shielded power inductors from Central Technologies. The series provides various inductance values within the same physical footprint, allowing for design flexibility. The 'AF' suffix typically denotes specific material or compliance characteristics defined by the manufacturer. This series is engineered for modern electronics requiring compact, reliable passive components.
Fixed Inductors Replacement Considerations
Consult the official Central Technologies replacement guide for direct equivalents. Verify that any substitute component matches the 1808 package dimensions, 22 µH inductance, and shielding requirements. Ensure compatibility with existing PCB footprints and thermal management strategies before implementing any alternative parts.
