Procurement Notes

Verify the specific suffix requirements for your design, as variants like 78250MC-R indicate different isolation ratings. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement orders to ensure regulatory adherence.

Selection Notes

Select this component when MAX250 compatibility is required alongside high isolation needs. Ensure the PCB footprint matches the specified dimensions. Consider thermal management capabilities within the stated operating temperature range during circuit layout.

Part Context

This part belongs to the 78250 series of specialty transformers manufactured by Murata Power Solutions. These components are engineered specifically for isolated DC-DC converter topologies requiring robust galvanic isolation between primary and secondary windings.

Replacement Considerations

Direct substitutes include the 78250JC-R variant, which offers similar functionality but may differ in isolation specifications. Verify pinout compatibility and electrical parameters before swapping components in existing designs.
