78604/8JC-R

Overview

The Murata Power Solutions Inc. 78604/8JC-R is a surface-mount general-purpose pulse transformer from the 786J series. It features a primary-to-secondary turns ratio of 2:1 and an inductance of 850µH. The component has an ET rating 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 capability
• RoHS3 compliant manufacturing

Applications

• Gate drive circuits
• Isolated power supply feedback loops
• Signal transmission in switching applications

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm that the 78604/8JC is a parameter-equivalent alternative if reel packaging is not required. Check current availability as lead times may vary. Ensure the design accommodates the specified 9.52mm x 9.00mm footprint and 6.35mm height constraints.

Selection Notes

Select this component for designs requiring a 2:1 step-down or step-up ratio with high inductance. The 850µH value supports specific energy transfer requirements. Verify compatibility with the target switching frequency and voltage levels against the 15Vµs ET limit. Ensure the operating environment stays within the 0°C to 70°C range.

Part Context

This part belongs to the 786J series of SMT pulse transformers. It shares the standard 6-pin package form factor common to the 78604 family. The 'JC' designation typically denotes specific insulation and electrical characteristics within this product line, while 'R' specifies the tape and reel delivery method.

Replacement Considerations

The 78604/8JC is listed as a parameter-equivalent substitute. This alternative offers identical electrical specifications but utilizes tube packaging instead of the reel format found in the 78604/8JC-R.
