• Standard tolerance specification for inductance

Fixed Inductors Applications

• DC/DC converter circuits
• Notebook computer power systems
• Mobile appliance electronics

Fixed Inductors Procurement Notes

Verify the exact physical footprint against the manufacturer's mechanical drawing prior to procurement, as the component is designated as having a nonstandard package size. Confirm that the 2.8 A current rating aligns with the thermal requirements of the target application environment. Ensure compatibility with standard surface mount reflow soldering profiles during assembly planning.

Fixed Inductors Selection Notes

Select this component when a compact, unshielded toroidal inductor is required for low-power DC/DC conversion applications. The 12 µH value suits general filtering needs in portable devices. Consider the nonstandard package dimensions carefully to ensure adequate PCB real estate. Verify that the 46 mΩ DCR meets efficiency targets for the specific circuit topology.

Fixed Inductors Part Context

This part belongs to the CTSPT30LF series of surface-mount toroidal inductors from Central Technologies. The series includes various inductance values, such as the CTSPT30LF-353M, sharing similar form factors. These components are designed for high-density mounting in consumer electronics and computing hardware where space constraints are critical.

Fixed Inductors Replacement Considerations

Cross-reference with other SMD toroidal inductors offering 12 µH ±20% tolerance and similar current ratings. Ensure substitute parts accommodate the nonstandard footprint or adjust PCB layout accordingly. Verify that replacement components maintain equivalent unshielded characteristics to avoid unintended electromagnetic interference changes.
