Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify availability through authorized distributors as stock may be limited. Confirm end-of-life status directly with Murata Electronics before finalizing procurement plans to ensure supply chain continuity.
Selection Notes
Select this inductor for applications requiring high current handling in compact power systems. The 1.7 µH value supports efficient energy storage in switching regulators. Ensure the nonstandard footprint fits the PCB layout constraints and verify thermal requirements against the 85°C maximum operating limit.
Part Context
Part of the B953AS series of fixed power inductors designed for surface mount technology. This specific model provides a balance of low resistance and high current capacity, distinguishing it from lower-current variants within the same product family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolescence status, alternative components must be sourced based on matching electrical specifications such as 1.7 µH inductance and 7.7 A saturation current.
