- RoHS compliant manufacturing process
Applications
- Power line choke applications
- General purpose power filtering circuits
- Surface mount power supply designs
Procurement Notes
Verify the specific suffix P3 against official Murata documentation to confirm packaging and terminal specifications. Confirm current lifecycle status as distribution data indicates potential end-of-life or discontinuation phases. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component for applications requiring 18 µH inductance with a 2 A current rating. The shielded design is suitable for noise-sensitive environments. Verify that the 79 mΩ DCR meets the efficiency requirements of the target circuit design.
Part Context
This part belongs to the B952AS series of fixed power inductors. It shares the same physical footprint and shielding technology as other variants in the family, differing primarily in inductance value and current handling capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Muratec technical support for direct replacements.
