Overview
The #B966BS-560M=P3 is a shielded drum core, wirewound power inductor manufactured by Murata Electronics. It features an inductance of 56 µH with a tolerance of ±20%. The component supports a maximum current rating of 1.6 A and a saturation current (Isat) of 1.6 A. Its maximum DC resistance (DCR) is 145 mΩ. The physical dimensions are 10.40 mm x 10.40 mm in footprint with a maximum height of 6.80 mm. It utilizes a ferrite core material and is designed for surface mount installation.
Feature Summary
- Shielded drum core construction minimizes electromagnetic interference
- Wirewound design ensures stable inductance characteristics
- Surface mount package facilitates automated assembly
Applications
- Power supply filtering circuits
- DC-DC converter input/output stages
- Signal processing choke applications
Procurement Notes
Verify the specific suffix =P3 to confirm packaging configuration, as it dictates shipping format rather than electrical function. Confirm RoHS3 compliance status if required by your manufacturing standards. Check for active obsolescence notices or PCN documents from Murata, as availability may be limited. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing procurement orders.
Selection Notes
Select this component when a 56 µH inductance value is required within a compact 10.40mm square footprint. The 1.6 A current rating suits moderate power applications where space constraints preclude larger through-hole alternatives. Verify that the 145 mΩ DCR aligns with your efficiency targets. Consider the shielded design if EMI sensitivity is a primary concern in the target circuit layout.
Part Context
This part belongs to the B966BS series of fixed power inductors from Murata Electronics. The series is characterized by shielded drum core technology and surface mount compatibility. Other variants in the family share similar physical dimensions but differ in inductance values and current ratings, such as the 18 µH or 68 µH equivalents.
Replacement Considerations
Direct substitutes include other Murata B966BS variants with identical footprints but different inductance values, provided the circuit tolerates the change. Cross-brand replacements require matching the 10.40x10.40mm footprint, 56 µH nominal value, and 1.6 A current handling capability.
