Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tolerance specifications. Confirm that the requested part number matches the exact electrical parameters required for the circuit design, particularly the 10 nH inductance and 500 mA current rating. Cross-reference the RoHS3 compliance status and MSL level 1 classification with project requirements before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-self-resonant-frequency solution is required in a minimal footprint. The unshielded construction may necessitate careful PCB layout to minimize electromagnetic interference with adjacent traces. Ensure the application current does not exceed the 500 mA rated limit to prevent saturation or thermal issues. Consider the 170 milliohm DCR impact on overall circuit efficiency during power delivery stages.

Fixed Inductors Part Context

This component belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series utilizes a drum core wound architecture optimized for high-frequency performance. Similar parts in the lineup include variants with different inductance values such as 0402HM-220EKTS, which shares the same physical dimensions and construction style but offers higher inductance and lower current handling capabilities.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 0402 package, 10 nH nominal value, and similar current ratings. Verify that alternative manufacturers' components maintain comparable self-resonant frequencies and Q factors at 100 MHz. Ensure thermal characteristics and mounting compatibility are identical to avoid reflow profile adjustments.
