Fixed Inductors Procurement Notes

Verify the manufacturer part number WB1008TR39SG against official Cal-Chip Electronics documentation to confirm specifications. Ensure the supplier provides valid traceability and authenticity certificates. Check that the component matches the required 1008 package dimensions and electrical ratings for your specific circuit design before finalizing the order.

Fixed Inductors Selection Notes

Select this component when a 390 nH inductance with tight ±2% tolerance is required in a compact 1008 footprint. Consider the 470 mA current rating and 1.12 Ohm DC resistance limits for power handling. The unshielded design may require layout considerations for electromagnetic interference compared to shielded alternatives.

Fixed Inductors Part Context

This inductor belongs to the WB series from Cal-Chip Electronics, which specializes in surface-mount passive components. The 1008 case size indicates a standard metric dimension suitable for high-density PCB layouts. As a wirewound type, it offers stable performance for general electronic applications requiring precise inductance values.

Fixed Inductors Replacement Considerations

Cross-reference other manufacturers offering 390 nH ±2% inductors in 1008 packages. Verify compatibility regarding DC resistance, current rating, and physical footprint dimensions to ensure direct substitution without circuit modification.
