Fixed Inductors Procurement Notes

Verify the specific ordering suffix and package dimensions against the official Central Technologies datasheet prior to procurement. Confirm that the requested quantity aligns with available stock levels, as availability may fluctuate. Ensure compliance with RoHS requirements if applicable to the end product. Cross-reference the manufacturer part number with distributor catalogs to confirm authenticity and correct revision status before finalizing purchase orders.

Fixed Inductors Selection Notes

Select this component when a 1.2 µH inductance value is required with a minimum saturation current rating of 2.2 A. The low DCR of 44 mΩ makes it suitable for efficiency-sensitive power designs. Consider the physical footprint and shielding requirements of the target application to ensure compatibility with the PCB layout and thermal management strategy.

Fixed Inductors Part Context

This component belongs to the CTSPI3D18F series of shielded power inductors from Central Technologies. The series offers various inductance values tailored for different current requirements. The '1R2' designation specifically indicates the 1.2 µH value, while the 'F' suffix typically denotes the tolerance or packaging variant within the manufacturer's nomenclature system.

Fixed Inductors Replacement Considerations

Direct substitutes include other shielded power inductors with matching 1.2 µH inductance, similar saturation current ratings, and compatible physical dimensions. Verify pinout and electrical characteristics such as DCR and operating temperature range before substitution.
