78250MVC-R

Overview

The Murata Power Solutions 78250MVC-R is a surface-mount power transformer designed for MAX250/MAX251 converter applications. It features an inductance of 2.5 mH and supports isolation voltages up to 4 kVDC. The component utilizes a compact SMD package with dimensions of 9.52 mm length, 9.00 mm width, and 6.35 mm height. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Designed specifically for MAX250/MAX251 DC-DC converter circuits
• Provides high voltage isolation capability up to 4 kVDC
• Optimized for surface-mount assembly processes

Applications

• RS-232 data interface applications
• Industrial automation systems
• Process automation equipment

Procurement Notes

Verify the specific suffix 'MVC-R' against official Murata documentation to confirm the 4 kVDC isolation rating and surface-mount configuration. Ensure compatibility with MAX250/MAX251 controller designs. Confirm that the component status aligns with current design-in requirements, as availability may vary.

Selection Notes

Select this component when designing MAX250/MAX251-based converters requiring high isolation and surface-mount integration. Compare the 2.5 mH inductance and 4 kVDC rating against system isolation requirements. Evaluate the physical footprint constraints against the 9.52 x 9.00 mm dimensions.

Part Context

This part belongs to the 78250 series of power transformers from Murata Power Solutions. The series includes variants such as 78250VC (through-hole) and 78250MC-R (lower isolation). The MVC-R variant specifically addresses applications needing enhanced isolation in a compact surface-mount form factor.

Replacement Considerations

Direct substitutes include other 78250 series variants like 78250JC-R or 78250MC-R, provided the isolation voltage and mounting style differences are acceptable for the specific application design.
