Procurement Notes

Verify the manufacturer designation carefully, as distributor listings may associate this part number with Max Echo Technology Corp. while cross-referencing similar specifications from other brands like Bourns. Confirm that the specific ordering suffix matches the required inductance value and tolerance. Ensure the procurement channel sources genuine components directly from authorized distributors to guarantee AEC-Q200 certification validity and traceability for automotive or high-reliability deployments.

Selection Notes

Select this component when a low-inductance, unshielded solution is required for high-frequency applications. The 0402 package size offers a balance between current handling capability and board space efficiency. Consider the 300 mΩ DC resistance and 400 mA current rating to ensure thermal stability under load. The unshielded design necessitates careful layout planning to minimize electromagnetic interference coupling with adjacent sensitive traces.

Part Context

This inductor belongs to the HBWS series, which utilizes precise wirewound technology for chip inductors. Max Echo Technology Corp. specializes in multilayer chip inductors and magnetic materials. The HBWS series targets both RF and power applications, leveraging ceramic cores to achieve high Q-factors and stable inductance values across varying temperature conditions.

Replacement Considerations

Cross-reference with CW105550A-30NJ from Bourns for identical electrical parameters and package dimensions. Verify that substitute parts maintain the same AEC-Q200 qualification status if used in automotive contexts. Ensure the replacement maintains the unshielded wirewound structure to preserve RF behavior and self-resonant frequency characteristics.
