78250JVC

Overview

The Murata Power Solutions 78250JVC is a board-mount power transformer designed for MAX250/MAX251 compatible converters. It features a surface mount installation style with dimensions of 9.00mm length, 9.52mm width, and 6.35mm height. The component has an inductance of 2 mH and supports a secondary current rating of 300 mA. It operates within a temperature range of -40°C to +85°C and includes a 4 kVDC isolation capability.

Feature Summary

• Designed specifically for compatibility with MAX250 and MAX251 converter integrated circuits
• Provides high voltage isolation rated at 4 kVDC between windings
• Utilizes a compact surface mount package suitable for automated assembly processes

Applications

• Power supply designs utilizing MAX250 or MAX251 controllers
• Board-level DC-DC conversion modules requiring galvanic isolation
• Compact electronic systems where space-constrained SMD transformers are required

Procurement Notes

Verify the specific suffix requirements for tape-and-reel packaging if continuous production is needed, as standard availability may vary by tube or reel configuration. Confirm that the 4 kVDC isolation rating meets the safety standards of the target application environment. Ensure the operating temperature range aligns with the thermal profile of the final device enclosure.

Selection Notes

Select this component when designing around MAX250/MAX251 architectures requiring a 2 mH inductance value. Consider the physical footprint of 9.00mm x 9.52mm for PCB layout constraints. Evaluate the 300 mA secondary current limit against the peak load requirements of the power stage to ensure adequate headroom during transient conditions.

Part Context

This part belongs to the 78250 series of specialty transformers from Murata Power Solutions. These components are engineered to complement Maxim Integrated (now Analog Devices) switching regulators. The series offers various mounting options including through-hole and surface mount variants to accommodate different manufacturing preferences and mechanical stress requirements.

Replacement Considerations

Direct substitutes include the 78250JC-R for surface mount applications without the specific 4 kVDC isolation emphasis, or the 78250MC-R. Verify pinout compatibility and inductance tolerance before swapping, as these parameters must match the original design specifications.
