Fixed Inductors Procurement Notes

Verify the specific suffix 'LF' against the manufacturer's official documentation to confirm lead-free compliance status and exact physical dimensions. Ensure the selected variant matches the required 1.1 µH inductance tolerance and 3.4 A current rating for the target circuit design. Cross-reference the nonstandard package outline with PCB footprint libraries prior to procurement to prevent assembly errors.

Fixed Inductors Selection Notes

Select this component for designs requiring a surface-mount toroidal inductor with high current capacity. The 1.1 µH value is suitable for intermediate frequency switching applications. Consider the unshielded nature when placing components near sensitive signal traces. The 130 °C operating temperature allows for robust performance in thermally constrained environments compared to standard 85 °C parts.

Fixed Inductors Part Context

This part belongs to the CTSPT-L series of surface-mount toroidal inductors manufactured by Central Technologies. The series offers various inductance values optimized for power supply filtering. The CTSPT20LF-112M specifically targets applications needing higher current ratings than smaller chip inductors while maintaining a low profile for space-constrained portable electronics.

Fixed Inductors Replacement Considerations

Direct substitutes include other surface-mount toroidal inductors with similar 1.1 µH inductance and >3.4 A current ratings. Verify that replacement parts match the nonstandard package dimensions and pin configuration. Ensure equivalent DC resistance and temperature ratings are maintained for thermal compatibility.
