Overview
The Murata #B953AS-3R9N=P3 is a shielded surface-mount power inductor from the B953AS series. It features a ferrite drum core and wirewound construction, providing an inductance of 3.9 µH with a ±20% tolerance. The component supports a maximum DC current of 6 A and a saturation current (Isat) of 7.9 A. Its maximum DC resistance is 14 mOhms. Operating within a temperature range of -40°C to +85°C, it utilizes a non-standard SMD package.
Feature Summary
- Shielded design utilizing a ferrite drum core and wirewound technology to minimize electromagnetic interference.
- High current handling capability with a 6 A continuous rating and 7.9 A saturation threshold.
Applications
- Power line chokes
- DC-DC converter output filtering
- General power supply input/output stages
Procurement Notes
Verify the specific suffix =P3 against the official datasheet to confirm packaging and material specifications. Confirm that the requested quantity aligns with the manufacturer's standard reel sizes or cut tape availability. Ensure the application environment remains within the specified -40°C to +85°C operating range for reliable performance.
Selection Notes
Select this component when high current density is required in a compact footprint. The 3.9 µH value suits applications needing moderate energy storage with low impedance. Compare the 14 mOhms DCR against system loss requirements. Consider the shielded type if EMI suppression is critical compared to unshielded alternatives.
