Procurement Notes
Verify the specific suffix =P3 against official Murata documentation to confirm packaging and compliance details. Confirm end-of-life status as indicated by recent PCN notices. Ensure compatibility with surface mount assembly processes given the non-standard package dimensions. Cross-reference manufacturer part numbers with distributor codes for accurate ordering.
Selection Notes
Select this component when high current handling up to 1.9 A is required alongside moderate inductance values. The shielded design minimizes magnetic field leakage, suitable for dense PCB layouts. Consider the physical footprint of 10.40 mm square when planning board space. Verify thermal requirements against the -40°C to +85°C operating range.
Part Context
This inductor belongs to the B952AS series from Murata Electronics, designed for power electronics applications. The series offers various inductance values with shielded wirewound technology. The =P3 suffix typically denotes specific packaging or compliance variations within the product line. It serves as a passive component for energy storage and filtering in electronic circuits.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Consult Murata's SimSurfing tool or official distributor databases for equivalent components with matching electrical specifications and footprint requirements.
