The component has a volt-second rating (ET) of 15Vµs and operates within a temperature range of 0°C to 70°C. Its physical dimensions are 9.52mm in length, 9.00mm in width, and a maximum height of 6.35mm. The device complies with RoHS3 standards.

Feature Summary

• Surface-mount construction for automated PCB assembly
• General-purpose isolation and coupling capability
• Center-tapped primary winding configuration

Applications

• Line coupling in digital communication circuits
• Impedance matching between signal stages
• Galvanic isolation in pulse transmission paths

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the manufacturer part number matches exactly, as variations exist within the 786 series. Check current lifecycle status, as some variants may be nearing end-of-life. Ensure design-in compatibility with existing footprint requirements before finalizing procurement.

Selection Notes

Select this component when a center-tapped primary is required for surface-mount designs. Compare the 1mH inductance and 15Vµs ET rating against circuit requirements. Consider the 78613/8C for through-hole alternatives if space allows. Verify thermal limits align with the intended operating environment.

Part Context

This part belongs to the Murata 786 series of general-purpose pulse transformers. The series offers various winding configurations and mounting styles. The 78613/4JC-R specifically addresses surface-mount needs with a center-tapped primary. Other series members include different ratios and inductance values for diverse application scenarios.

Replacement Considerations

The 78613/8C is a through-hole alternative within the same series. For SMD replacements, verify equivalent electrical parameters such as inductance and ET rating. Cross-reference with other 786J series parts if pinout or footprint constraints differ.
