• Low DC resistance of 0.47 mΩ to minimize conduction losses
• Wide operating temperature range from -40°C to 125°C for robust environmental performance
• Unshielded design suitable for general-purpose power filtering

Fixed Inductors Applications

• Power supply output filtering
• DC-DC converter input/output stages
• High-current power distribution networks

Fixed Inductors Procurement Notes

Verify the specific suffix 'H' against the manufacturer's datasheet to confirm mechanical and electrical specifications match the design requirements. Ensure the ordering quantity aligns with the standard packaging quantity of 500 units per reel. Confirm RoHS3 compliance status if required by local regulations. Check lead times as they are subject to manufacturer availability. Validate that the non-standard package fits the PCB footprint constraints.

Fixed Inductors Selection Notes

Select this component when high current capacity is critical, given the 37 A rating. The 300 nH value is suitable for higher frequency switching applications compared to larger inductances. Consider the unshielded nature for potential EMI implications in sensitive layouts. The low DCR makes it efficient for high-power density designs. Ensure the saturation current of 23 A meets the peak load requirements without significant inductance drop.
