Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure that the 1812 package dimensions align with the target PCB layout requirements. Cross-reference the 120 mA current rating against the actual operating conditions to prevent saturation or thermal issues during procurement validation.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable for the circuit design. Consider the 7 ohm DC resistance impact on voltage drop. Verify that the 120 mA current handling meets the peak load requirements. Confirm compatibility with standard SMT reflow processes for the 1812 form factor.

Fixed Inductors Part Context

Bourns Inc. acquired the J.W. Miller Magnetics Division, integrating their magnetic component portfolio. The PM series represents a line of surface mount power inductors. This model belongs to the broader category of unshielded molded inductors offered by the manufacturer for standard electronic assemblies.
