Overview
The #B953AS-101M=P3 is a shielded surface-mount power inductor from Murata Electronics, designed for high-current applications. It features a ferrite drum core and wirewound construction within a 12.8mm x 12.8mm footprint and 6.8mm height. The component provides an inductance of 100 µH with a ±20% tolerance. Key electrical parameters include a maximum DC resistance of 170 mOhms, a saturation current of 1.4 A, and a rated current of 1.4 A. It operates reliably between -40°C and +85°C.
Feature Summary
- Shielded magnetic structure minimizes electromagnetic interference
- Low DC resistance supports efficient power delivery
- Suitable for high-current DC-DC converter circuits
Applications
- DC-DC converter inductors
- Power line chokes
- High-current filtering applications
Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Availability is limited to existing stock or special factory orders. Verify end-of-life status and final shipment dates before committing to production designs. Alternative sourcing may require immediate qualification of replacement parts due to potential supply constraints.
Selection Notes
Select this part for applications requiring 100 µH inductance in a compact SMD package. Ensure design currents do not exceed the 1.4 A saturation limit. The shielded type reduces EMI compared to unshielded variants. Consider thermal management within the specified -40°C to +85°C operating range during PCB layout.
Part Context
Part of the B953AS series, characterized by large planar dimensions up to 12.8mm and low DCR. Designed for robust performance in power electronics. The =P3 suffix indicates specific packaging or compliance variations consistent with Murata's standard nomenclature for this product line.
Replacement Considerations
Public confirmed substitute part numbers are not explicitly listed in the provided source documentation. Consult official Murata SimSurfing tools or distributor cross-reference lists for verified alternatives.
