Procurement Notes

Verify the specific suffix -R indicates reel packaging versus tube variants like the standard 78615/9JC. Confirm RoHS compliance status through official documentation. Ensure surface mount footprint compatibility with assembly equipment. Cross-reference datasheet specifications against circuit requirements to validate electrical performance limits.

Selection Notes

Select this component when surface mount topology is required for 1:1 pulse transformation. The 10 mH inductance and 56 Vµs rating define its operational bandwidth and energy handling. Compare physical dimensions against board space constraints. Evaluate the 1.45 ohm DC resistance impact on signal integrity within the target application circuit design parameters.

Part Context

This part belongs to the Murata 786J series of pulse transformers. The series includes various winding configurations and mounting styles. The 78615/9JC-R variant specifically utilizes surface mount technology. Other series members may differ in inductance, voltage ratings, or package type while sharing similar core technologies.

Replacement Considerations

The standard 78615/9JC is a tube-packaged equivalent with identical electrical characteristics. Verify that the reel packaging difference does not affect mechanical fit or assembly processes. No other direct substitutes are documented in the provided source material.
