Fixed Inductors Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct tolerance and packaging configuration. Confirm that the required operating temperature range aligns with the component's -40°C to 125°C specification. Cross-reference the DCR and rated current values with circuit requirements to prevent thermal issues during operation.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 25 nH is required for high-frequency signal paths. The unshielded nature necessitates careful PCB layout to minimize electromagnetic interference coupling with adjacent traces. Ensure the board space accommodates the 0402 package dimensions and that the assembly process supports the specified maximum height.

Fixed Inductors Part Context

This part belongs to the 0402HP series of fixed inductors manufactured by Delta Electronics/Components. The series utilizes wirewound technology on a drum core with ceramic materials. It is distinct from the 0402HC series, which offers different inductance ranges and physical dimensions. The product is currently active and RoHS3 compliant.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include 0402HP-150EHTS for lower inductance applications. Other variants in the 0402HP family may offer different current ratings or tolerances. Verify pinout and mechanical dimensions before substituting with components from other manufacturers.
