Fixed Inductors Procurement Notes

Verify the RoHS compliance status by checking the specific ordering suffix or manufacturer documentation, as lead-free variants may exist within the series. Confirm that the 2.7 A rated current aligns with your thermal management requirements. Ensure the 4.0x4.0x2.0 mm footprint matches your PCB layout constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact, shielded inductor is required for space-constrained power designs. The 4.7 µH value suits intermediate frequency switching applications. Consider the 91 mΩ DCR impact on efficiency. Compare against unshielded alternatives if EMI is not a primary concern, noting the trade-off between size and magnetic containment.

Fixed Inductors Part Context

This part belongs to the CTSPMA series of shielded power inductors manufactured by Central Technologies. The series offers various inductance values and current ratings within a standardized small outline package. It is intended for high-volume consumer electronics manufacturing where reliability and size reduction are critical priorities.

Fixed Inductors Replacement Considerations

Direct substitutes include other 4.7 µH shielded SMD inductors with similar current ratings and dimensions. Verify pinout compatibility and thermal characteristics. Cross-reference with CTSPMA4015F-4R7M for height variations or other manufacturers' equivalent footprints.
