78615/3JC

Overview

The Murata Power Solutions 78615/3JC is a surface-mount pulse transformer designed for general-purpose applications. It features a 1CT:1CT turns ratio and an inductance of 190 µH. The component operates within a temperature range of 0°C to +70°C and complies with RoHS3 standards. Its physical dimensions are 9.52 mm in length, 9.00 mm in width, and a maximum height of 6.35 mm. The device utilizes a toroidal core construction suitable for high-frequency signal transmission.

Feature Summary

• Surface-mount topology optimized for automated PCB assembly processes
• Toroidal core design providing efficient magnetic coupling
• Compliance with RoHS3 environmental regulations

Applications

• General-purpose signal isolation circuits
• Gate drive interface transformers
• Pulse transmission in industrial control systems

Procurement Notes

Verify the specific suffix configuration against official Murata documentation to ensure correct winding polarity and electrical characteristics. Confirm that the surface-mount package dimensions align with the target PCB footprint. Check current availability status as manufacturing schedules may vary. Ensure compliance with project-specific environmental requirements such as RoHS3 certification before finalizing procurement orders.

Selection Notes

Select this component when a 190 µH inductance and 1CT:1CT ratio are required for surface-mount designs. Consider the 6.35 mm maximum height constraint for low-profile board layouts. Evaluate thermal performance within the 0°C to +70°C operating range. Compare against other series members if different inductance values or through-hole mounting options are necessary for the application.

Part Context

This part belongs to the Murata 786J series of pulse transformers. The series offers various inductance values and winding configurations tailored for different signal integrity requirements. The 78615/3JC specifically addresses needs for moderate inductance in compact surface-mount form factors, distinguishing it from higher-inductance or through-hole variants within the broader product family.

Replacement Considerations

The 78615/9JC-R is a documented alternative within the same series offering similar surface-mount characteristics.
