Fixed Inductors Procurement Notes
Verify the specific part number against official Central Technologies documentation to confirm electrical parameters and mechanical dimensions. Ensure that the procurement source provides valid datasheets matching the CTMMP1805F series specifications. Cross-reference the manufacturer's latest release notes for any updates regarding compliance or package variations before finalizing orders.
Fixed Inductors Selection Notes
Select this component when a compact, shielded inductor is required for high-current DC-DC conversion. The 2.2 µH value and 3.5 A rating suit low-voltage, high-amperage circuits. Consider the 1.20 mm height limit for strict board clearance requirements. Compare against unshielded alternatives if cost is the primary driver, though EMI performance may differ.
Fixed Inductors Part Context
This model belongs to the CTMMP1805F series, which consists of shielded SMD power inductors designed for portable and computing electronics. The series offers various inductance values within a standardized footprint, allowing designers to maintain consistent board layouts while adjusting circuit parameters for different power stages.
Fixed Inductors Replacement Considerations
Direct substitutes include other Central Technologies shielded power inductors with identical 1805 footprints and similar electrical ratings. Verify that alternative parts match the 2.2 µH inductance, 3.5 A current rating, and 8.5 mΩ DCR specifications to ensure circuit compatibility.
