Fixed Inductors Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging containing 500 pieces per reel. Confirm RoHS3 compliance status matches current regulatory requirements. Ensure the 1812 package footprint aligns with PCB layout specifications. Check that the 390 mA current rating meets circuit load demands without saturation.

Fixed Inductors Selection Notes

Select this component when a compact 1812 form factor is required for power management applications. The 1.8 µH value suits intermediate frequency filtering tasks. Consider the 650 mOhm DCR for efficiency calculations in low-current designs. Verify thermal performance at the upper operating limit of 85°C.

Fixed Inductors Part Context

This part belongs to the AISM-1812 series of shielded power inductors from Abracon. The series offers various inductance values within the same physical envelope. It serves as a standard solution for space-constrained consumer and industrial electronics requiring reliable SMD inductance.

Fixed Inductors Replacement Considerations

Cross-reference with other 1812 wirewound inductors offering 1.8 µH ±10% tolerance. Ensure substitute parts match the 390 mA current rating and 650 mOhm DCR limits. Verify identical package dimensions for direct PCB replacement.
