78604/4JC-R

Overview

The Murata Power Solutions 78604/4JC-R is a general-purpose pulse transformer featuring a 2:1 turns ratio and an inductance of 65µH. Designed for surface-mount installation, it measures 9.52mm in length, 9.00mm in width, and 6.35mm in height. The component supports a voltage-time product (Et) of 4V/µs and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Surface-mount construction for automated PCB assembly
• General-purpose design with 2:1 turns ratio
• Compact footprint suitable for space-constrained layouts

Applications

• Gate drive circuits for power switching devices
• Pulse isolation in digital communication interfaces
• Signal coupling in isolated power supply topologies

Procurement Notes

Verify the specific suffix JC-R against the official datasheet to confirm exact electrical tolerances and packaging configuration. Ensure the selected variant matches the required surface-mount pad layout and thermal specifications for the target application environment.

Selection Notes

Select this component when a compact surface-mount pulse transformer with a 2:1 ratio is required. Compare the 65µH inductance and 4V/µs Et rating against circuit requirements. Consider the 0°C to +70°C operating range for environmental compatibility.

Part Context

This part belongs to the Murata 786 series of pulse transformers. It shares the same physical dimensions as other variants in the family but differs in electrical parameters such as inductance and turns ratio. The JC-R suffix indicates a specific manufacturing configuration within this series.

Replacement Considerations

The 78604/4MC-R is listed as a similar alternative. Verify that its 67µH inductance and identical package dimensions are compatible with the existing design before substitution.
