#B966AS-120M=P3

Overview

The #B966AS-120M=P3 is a shielded drum core wirewound power inductor manufactured by Murata Electronics. It features a nominal inductance of 12 µH and supports a continuous RMS current rating of 3.7 A. The component exhibits a maximum DC resistance of 35 mOhm and a saturation current of 3.9 A. Designed for surface mount technology, it utilizes a nonstandard package configuration suitable for PCB mounting applications.

Feature Summary

Shielded drum core construction minimizes electromagnetic interference
Wirewound design ensures stable performance under load
High current handling capability with low DC resistance

Applications

Power supply output filtering
DC-DC converter energy storage
General purpose power circuitry

Procurement Notes

Verify the exact physical dimensions against your PCB footprint due to the nonstandard package designation. Confirm that the 3.7 A RMS and 3.9 A saturation current ratings align with your thermal management requirements. Ensure the manufacturer part number matches exactly, as suffixes can indicate specific packaging or testing variations.

Selection Notes

Select this component when a shielded inductor is required to prevent magnetic coupling issues in dense layouts. The 12 µH value suits moderate frequency switching applications. Consider the 35 mOhm resistance for efficiency calculations. Verify availability status as distribution channels may report varying stock levels.

Part Context

This part belongs to Murata's fixed inductor portfolio, specifically within the power inductor category. It represents a specialized solution for applications requiring robust current handling in a compact form factor. The product line focuses on reliability and electromagnetic compatibility for modern electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching inductance, current ratings, and physical dimensions manually.
