Procurement Notes
Verify the specific suffix SMLF against official Gowanda documentation to confirm surface mount compatibility and lead finish specifications. Ensure the operating temperature range aligns with system thermal requirements. Cross-reference the 70 mΩ DCR limit with circuit loss calculations. Confirm RoHS compliance status through the manufacturer's latest datasheet revision.
Selection Notes
Select this component when a shielded toroidal inductor with 25 µH inductance is required for surface mount designs. Evaluate the 2.16 A current rating against peak load conditions. Consider the -55°C to 130°C operational range for environmental suitability. Compare the 70 mΩ resistance against efficiency targets in power conversion topologies.
Part Context
This component belongs to Gowanda Electronics' fixed inductor portfolio, specifically designed for robust power handling. The 030AT series denotes shielded toroidal variants optimized for high-current applications. The SMLF suffix indicates surface mount packaging with lead-free termination, distinguishing it from through-hole alternatives within the same inductance family.
Replacement Considerations
Consult Gowanda Electronics for direct cross-references. Verify pinout compatibility and inductance tolerance before substituting. Ensure equivalent shielding characteristics to prevent EMI issues in dense layouts.
