Additional Details
The BD3511NV-E2 typically comes in a small surface-mount package such as a VSON (Very Small Outline No-lead) package. Key electrical characteristics include output power, supply voltage range, and total harmonic distortion (THD). The '-E2' suffix likely indicates a specific packing specification (e.g., RoHS compliance and reel size). Consult the Rohm Semiconductor datasheet for detailed specifications and application guidelines.
