Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm the tolerance code, as variations exist within the series. Ensure the procurement documentation explicitly states the 220 nH inductance value and 700 mΩ DC resistance. Confirm that the component matches the 0805 surface mount package dimensions. Cross-reference the manufacturer part number against official Central Technologies catalogs to avoid substitution errors.

Fixed Inductors Selection Notes

Select this component when a compact surface mount inductor with low inductance values is required. The 0805 footprint offers a balance between size and current handling capabilities. Consider the 700 mΩ DC resistance for efficiency calculations in low-power circuits. Verify thermal requirements against the specified operating temperature range of -40 °C to +125 °C for the intended application environment.

Fixed Inductors Part Context

This part belongs to the CT0805CSF series from Central Technologies, which covers a wide range of fixed inductances from 2.2 nH to higher values. The series is characterized by its ceramic core construction and surface mount compatibility. Components in this line are generally designated for general-purpose electronic applications requiring reliable passive components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 220 nH ±10% surface mount inductors from Central Technologies such as the CT0805CSF-221J or CT0805CSF-221M, provided the tolerance codes align with design requirements. Verify pinout and physical dimensions before replacing with components from different manufacturers.
