• DC-DC converter modules
• General electronic equipment requiring SMD power inductors

Fixed Inductors Procurement Notes

Verify the specific suffix =P3 against official Murata documentation to confirm compliance with RoHS3 standards and REACH requirements. Ensure that the selected packaging format, such as cut tape or reel, matches the intended manufacturing process. Cross-reference the manufacturer part number with distributor catalogs to confirm availability status and lead times prior to ordering.

Fixed Inductors Selection Notes

Select this component when a compact 8.00 mm x 8.00 mm footprint is required for power filtering applications. The 6.1 A rated current and low DCR make it suitable for moderate power density designs. Consider the ±30% tolerance and saturation characteristics during circuit simulation to ensure stability under varying load conditions compared to alternative series like 1274AS.

Fixed Inductors Part Context

This inductor belongs to the DEM8045C series manufactured by Murata Electronics. It is categorized under fixed power inductors designed for surface-mount technology. The product line focuses on providing reliable shielding and thermal performance for modern electronic devices requiring efficient energy storage and noise suppression in compact form factors.

Fixed Inductors Replacement Considerations

The DD1217AS-H-3R3N=P3 offers similar electrical specifications but utilizes a larger 10.00 mm x 10.00 mm package. Designers must account for the increased footprint and potential differences in saturation current when substituting components within the same Murata portfolio.
