#B953AS-390M=P3

Overview

The Murata #B953AS-390M=P3 is a shielded drum core, wirewound surface mount inductor with a nominal inductance of 39 µH. It features a maximum DC resistance of 74 mΩ and supports a saturation current of 2.2 A. The component operates within a temperature range of -40°C to +85°C and utilizes an iron ferrite core material.

Feature Summary

Shielded drum core construction minimizes electromagnetic interference
Wirewound design ensures stable performance under load
Surface mount package facilitates automated assembly

Applications

DC-DC converter output filtering
Power supply input stages
General-purpose energy storage in power management circuits

Procurement Notes

Verify the =P3 suffix for specific packaging configuration. Confirm RoHS3 compliance status prior to integration. Check for End-of-Life notices as obsolescence may affect long-term availability. Validate lead times due to potential supply constraints.

Selection Notes

Select this component when a 39 µH value with 2.2 A saturation current is required. Ensure the nonstandard footprint matches the PCB layout. Compare DCR and thermal characteristics against alternative shielded inductors for space-constrained designs.

Part Context

This part belongs to the B953AS series of fixed inductors from Murata Electronics. The series offers various inductance values tailored for compact power electronics applications. The =P3 suffix typically denotes tape and reel packaging for high-volume manufacturing.

Replacement Considerations

Consult official substitution lists for equivalent shielded drum core inductors. Verify pin compatibility and electrical parameters before replacing. Consider lifecycle status when selecting alternatives.
