Fixed Inductors Procurement Notes

Verify component status as the PM1812-151J is listed as obsolete or discontinued by the manufacturer. Confirm availability through secondary market distributors if procurement is required. Ensure that any sourced units match the original datasheet specifications regarding electrical parameters and physical dimensions before integration into production.

Fixed Inductors Selection Notes

Select this component for designs requiring a 150 µH inductance in an 1812 footprint. Consider the 105 mA current limit and 9 ohm DC resistance when calculating voltage drops and thermal performance. The unshielded design may require layout considerations to manage electromagnetic interference in dense circuit boards.

Fixed Inductors Part Context

This part belongs to the Bourns PM series of surface mount power inductors. The series includes various inductance values and package sizes, such as the PM1608 and PM1210 variants. The PM1812-151J specifically targets applications needing higher inductance in a standard SMD form factor compared to smaller packages.

Fixed Inductors Replacement Considerations

As the PM1812-151J is discontinued, verify equivalent parts from other manufacturers offering similar 150 µH, 1812 package inductors. Check for matching current ratings, DC resistance, and self-resonant frequency to ensure functional compatibility in existing designs.
