Fixed Inductors Procurement Notes

Verify the specific suffix SJ confirms the ±5% tolerance and 180 nH value against the manufacturer datasheet. Confirm the 1008 package dimensions match the required PCB footprint. Ensure the 620 mA current rating meets the operational requirements of the target circuit to prevent saturation or thermal issues during procurement validation.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-precision solution is required for space-constrained designs. The unshielded nature may necessitate layout considerations regarding magnetic interference. Compare the 770 mΩ DC resistance against power loss constraints. Verify that the 620 mA current handling capability aligns with the peak and continuous load currents of the application.

Fixed Inductors Part Context

This part belongs to the WB1008 series of fixed inductors from Cal-Chip Electronics. The series offers various inductance values within the 1008 SMD package. This specific model represents a standard general-purpose option suitable for consumer electronics and industrial control boards requiring compact passive components.

Fixed Inductors Replacement Considerations

Cross-reference with other 180 nH ±5% inductors in the 1008 package. Verify equivalent DC resistance and current ratings. Check if shielded variants are acceptable if EMI mitigation is required. Confirm pin compatibility and thermal characteristics before substitution.
