Procurement Notes

Verify current availability status as the component is marked Not Recommended for New Designs (NRND). Confirm compatibility with existing PCB footprints and thermal requirements before finalizing procurement plans. Check for suggested alternate part numbers provided by the manufacturer to ensure long-term supply chain stability.

Selection Notes

Select this component when designing for specific digital audio data transmission frequencies between 50 Hz and 60 Hz. Ensure the design accommodates the 2 kV insulation voltage requirement and the specified inductance range. Consider the NRND status when planning for future production runs or product lifecycle management.

Part Context

This transformer belongs to the Audio & Signal Transformers category from Murata Power Solutions. It is specifically engineered for transmitting digital audio data, distinguishing it from general-purpose power transformers. The SMD-6 package allows for compact integration into modern electronic devices requiring signal integrity and isolation.

Replacement Considerations

Murata suggests the DA103JC-R as an alternate part number. Verify electrical compatibility and physical dimensions before substitution.
