Fixed Inductors Procurement Notes

Verify the specific suffix code when ordering to confirm the tolerance level, as the series offers multiple options such as J for ±5%, K for ±10%, and M for ±20%. Ensure the selected variant matches the required precision for the target circuit design. Confirm compliance with environmental regulations if necessary for the final assembly process.

Fixed Inductors Selection Notes

Select this component based on the requirement for a 47 nH inductance value with tight ±2% tolerance. Consider the 0.6 A current rating and 0.28 Ω DC resistance for power loss calculations. Evaluate the 2 MHz self-resonant frequency to ensure it aligns with the operating frequency of the application, avoiding resonance issues in the intended signal band.

Fixed Inductors Part Context

This part belongs to the CT0603CSF series of wire-wound chip inductors from Central Technologies. The series covers a wide inductance range from 1.6 nH to 390 nH, all utilizing a ceramic core and available in the 0603 SMD package. Variants are distinguished by their tolerance codes, allowing designers to choose between different precision levels while maintaining consistent physical dimensions and mounting characteristics across the family.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 47 nH inductance, 0603 package, and similar electrical parameters. Verify that alternative components support comparable current ratings and have compatible self-resonant frequencies to maintain circuit performance without modification.
