Overview
The #B952AS-H-1R1N=P3 is a shielded drum core, wirewound power inductor from Murata Electronics. It features an inductance of 1.1 µH with a tolerance of ±30%. The component has a maximum DC resistance (DCR) of 11 mΩ and a rated current of 6 A. The saturation current (Isat) is 11.7 A. It operates within a temperature range of -40°C to 85°C or -40°C to 125°C depending on the source variant. Dimensions are 10.40mm x 10.40mm x 4.80mm max.
Feature Summary
- Shielded drum core construction minimizes electromagnetic interference
- High saturation current capability supports demanding power applications
- Low DC resistance reduces conduction losses
- Surface mount package facilitates automated assembly
Applications
- Power supply output filtering
- DC-DC converter energy storage
- Point-of-load regulation circuits
- Industrial power management systems
Procurement Notes
Verify the specific suffix and datasheet revision for the exact operating temperature range, as sources indicate variations between -40°C to 85°C and -40°C to 125°C. Confirm the part status, as some records list it as End-of-Life or Not Recommended for New Designs. Ensure the ordering code matches the required inductance value and current ratings for your design.
Selection Notes
Select this component when high current handling and low impedance are critical. The 11.7A saturation current allows for robust performance under load transients. Compare against alternative B952AS variants if different inductance values or physical footprints are required. Verify thermal management requirements given the power dissipation at rated currents.
Part Context
This part belongs to the B952AS series of power inductors designed for surface mount applications. It utilizes a ferrite core material and a shielded drum structure. The series is intended for use in modern electronic devices requiring efficient power conversion and compact component sizing.
Replacement Considerations
Public confirmed substitute part numbers include #B952AS-H-1R8N=P3, #B952AS-H-270M=P3, and #B952AS-H-2R7N=P3. These alternatives share the same physical footprint and series characteristics but offer different inductance values.
