Fixed Inductors Procurement Notes

Verify the specific manufacturer datasheet for the AISM-1812-180K-T to confirm current RoHS compliance status and exact packaging quantities. Ensure that the ordering suffix matches the required reel specifications. Cross-reference the part number with official Abracon documentation to validate availability and lead times through authorized distribution channels before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable for the circuit layout, as it may require careful placement to minimize electromagnetic interference coupling. The 1812 package size offers a balance between current handling capability and board space efficiency. Verify that the 190 mA saturation current meets the peak load requirements of the target power stage without causing excessive inductance drop.

Fixed Inductors Part Context

This component belongs to the AISM series of power inductors from Abracon LLC, which are engineered for compact electronic designs. The series utilizes molded wirewound techniques to provide stable inductance values across various operating conditions. These inductors are commonly integrated into portable devices and industrial control systems where reliable energy storage and filtering are critical for system stability.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 18 µH inductance, 1812 package dimensions, and similar current ratings. Verify compatibility with unshielded core types to ensure equivalent magnetic field characteristics. Consult manufacturer cross-reference lists for verified alternative part numbers that maintain identical electrical performance parameters.
