Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Cal-Chip Electronics documentation to confirm the ceramic core type and exact inductance value. Ensure that the procurement source provides valid compliance certificates for RoHS and lead-free status. Cross-reference the package dimensions with standard 0402 SMD specifications to guarantee compatibility with existing PCB footprints and assembly equipment.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 4.3 nH is required for high-frequency circuitry. The 0402 package size is suitable for space-constrained designs. Consider the ±5% tolerance for precision requirements. Verify that the ceramic core material aligns with the thermal and frequency characteristics needed for the specific application environment compared to other core types like iron powder or ferrite.
