Fixed Inductors Procurement Notes

Verify that the specific part number matches the required ceramic-core wirewound specification. Confirm lead-free status and RoHS compliance requirements against project standards. Ensure the 0603 package dimensions align with the target footprint. Validate the 0.018 µH inductance value and 2% tolerance meet circuit design constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-self-resonant-frequency solution is needed in a compact 0603 package. The wirewound ceramic-core design supports currents up to 0.7 A. Consider the 0.17 Ω DC resistance impact on series losses. The 2% tolerance provides precise control for sensitive RF tuning applications compared to wider tolerance alternatives.
