Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical characteristics and packaging options. Ensure compatibility with the target PCB footprint and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when high current handling and broad frequency attenuation are required in a small form factor. Consider the 100 V rating and 15 A capacity relative to the system's power bus specifications and environmental temperature constraints.

Part Context

This part belongs to the Murata EMIFIL BNX series, which specializes in block-style EMI filters. These components are engineered for high-performance noise suppression in compact electronic assemblies, particularly where standard discrete filters cannot meet size or performance demands.

Replacement Considerations

BNX023-01L is a documented variant within the same series offering similar mechanical dimensions but potentially different internal capacitance values.
