Fixed Inductors Procurement Notes

Verify the specific tolerance suffix (J or K) against project requirements, as the base model indicates available variations. Confirm RoHS compliance status through official documentation prior to integration. Ensure storage conditions align with manufacturer guidelines for ceramic-based components to maintain electrical stability over time.

Fixed Inductors Selection Notes

Select this component when low inductance values are required for high-frequency operation. The unshielded nature necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Evaluate the 1 A current rating against peak load conditions to prevent saturation. The 160 mOhm resistance impacts efficiency in power-sensitive designs.

Fixed Inductors Part Context

This part belongs to INPAQ's wirewound ceramic RF inductor series, designed for high-frequency performance. It complements their portfolio of multilayer chip beads and metal molding power inductors. The 2520 package size offers a balance between current handling and board space efficiency compared to smaller footprints.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 47 nH inductance, 1008 package dimensions, and similar DC resistance characteristics. Verify that alternative manufacturers offer comparable Q-factor specifications at 50 MHz. Cross-reference tolerance grades to ensure circuit stability remains within acceptable limits during replacement.
