Fixed Inductors Procurement Notes

Verify the specific suffix code when ordering to confirm tolerance requirements, as the series supports multiple tolerance options. Ensure the procurement documentation explicitly references the Central Technologies manufacturer sequence number CTML1206F to distinguish from similar generic components. Cross-reference the datasheet version date to ensure compatibility with current supply chain specifications.

Fixed Inductors Selection Notes

Select this component for applications requiring a 0.33 µH inductance in a standard 1206 footprint. Consider the 0.6 Ω DC resistance limit for efficiency calculations in low-current paths. The wide operating temperature range makes it suitable for environments subject to thermal variation. Verify that the unshielded or shielded variant matches the electromagnetic interference requirements of the target circuit design.

Fixed Inductors Part Context

This part belongs to the CTML1206F series of multi-layer chip inductors produced by Central Technologies. The series spans inductance values from 0.047 µH to 33 µH, providing engineers with standardized sizing options. The F designation typically indicates specific tolerance or packaging variations within the broader CTML1206 family line.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1206 ferrite-core inductors with 0.33 µH nominal value and ±10% tolerance. Verify pin compatibility and physical dimensions before swapping manufacturers. Alternative part numbers may exist within the same series but require confirmation of identical electrical parameters such as DC resistance and self-resonant frequency.
