Fixed Inductors Procurement Notes

Verify the specific datasheet version provided by the manufacturer or authorized distributor to confirm exact electrical tolerances and mechanical dimensions. Ensure that the axial lead spacing matches the target PCB footprint requirements. Confirm RoHS compliance status if required for the specific assembly process. Cross-reference the part number suffixes to ensure no variations in shielding or current ratings exist between different production batches.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required for low-frequency filtering in through-hole designs. The unshielded nature may require consideration for electromagnetic interference in dense layouts. Compare the 0.4 A current rating against peak load requirements to prevent saturation. Evaluate the 2.3 Ω DC resistance impact on voltage drop within the specific circuit topology before finalizing the design.

Fixed Inductors Part Context

This component belongs to the CTH7F series of fixed inductors produced by Central Technologies. The series offers various inductance values tailored for power supply applications. The '102' designation indicates the 1000 µH value, while 'K' denotes the ±10% tolerance. These parts are distinct from shielded toroidal or surface-mount variants within the broader product catalog.

Fixed Inductors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic axial power inductors having matching 1000 µH inductance, 0.4 A minimum current rating, and ≤2.3 Ω DC resistance. Ensure physical axial lead spacing allows for direct pin-to-pin replacement without PCB modification.
