Fixed Inductors datasheet and documents for SPM4015T-3R3M-CA

SPM4015T-3R3M-CA

Fixed Inductors Overview

The TDK SPM4015T-3R3M-CA is a fixed power inductor from the SPM-CA series, designed for surface-mount applications. It features a shielded drum core wirewound construction with an iron powder magnetic material. The component provides an inductance of 3.3 µH with a ±20% tolerance, tested at 100 kHz. It supports a maximum rated current of 2.3 A and a saturation current (Isat) of 6.8 A. The DC resistance (DCR) is maximized at 128 mΩ. Physical dimensions are 4.40 mm in length, 4.10 mm in width, and 1.50 mm in height. It operates within a temperature range of -40°C to 125°C.

Fixed Inductors Feature Summary

Shielded drum core wirewound design minimizes electromagnetic interference.
High saturation current capability ensures stable performance under load.
RoHS3 compliant and REACH unaffected for regulatory adherence.

Fixed Inductors Applications

Power supply circuits
DC-DC converter modules
Point-of-load regulation

Fixed Inductors Procurement Notes

Verify the specific suffix 'CA' against the official TDK datasheet to confirm the exact electrical parameters, as series variants may differ. Confirm that the component status is active or acceptable for new designs, noting that some related parts may have discontinuation notices. Ensure the package type matches the PCB footprint requirements before ordering.

Fixed Inductors Selection Notes

Select this component when a compact 4015 footprint is required with high current handling. Compare the 128 mΩ DCR and 6.8 A Isat against circuit requirements. Consider the SPM-LR series if lower cost is prioritized over the specific CA series characteristics. Verify thermal management needs given the 125°C operating limit.

Fixed Inductors Part Context

This part belongs to the TDK SPM-CA series of fixed power inductors. These components are engineered for space-constrained electronics requiring reliable shielding. The series utilizes iron powder cores to balance inductance stability with saturation performance. It is distinct from the SPM-LR series, which offers different electrical trade-offs.

Fixed Inductors Replacement Considerations

Public confirmed substitutes include the SPM4015T-3R3M-CA02 from TDK. Alternative manufacturers such as Vishay Dale offer similar form-factor inductors like the IHLP series, though electrical parameters must be verified for compatibility.
