Fixed Inductors Procurement Notes

Verify the suffix MED against official Coilcraft documentation to confirm specific termination plating or tape-and-reel specifications. Ensure the selected variant matches the required thermal rating and current handling capabilities for the target application environment. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity.

Fixed Inductors Selection Notes

Select this component when high-temperature stability and compact shielding are required. The 18 µH value suits moderate-frequency switching applications. Evaluate the 2.28 A saturation current against peak load requirements. Consider the 49 mΩ DCR for loss calculations. Confirm that the 150°C rating exceeds the system's ambient thermal constraints.
