78604/3JC

Overview

The Murata Power Solutions Inc. 78604/3JC is a surface mount pulse transformer from the 786 series, designed for general-purpose applications. It features a primary-to-secondary turns ratio of 2:1 and an inductance of 67µH. The component has an ET (volt-time) rating of 6Vµs and operates within a temperature range of 0°C to 70°C. Its physical dimensions are 9.52mm in length, 9.00mm in width, with a maximum height of 6.35mm.

Feature Summary

• Surface mount construction for automated assembly
• General-purpose pulse transformer design
• RoHS3 compliant manufacturing

Applications

• Power supply circuits
• Isolation barriers in electronic systems
• Signal coupling applications

Procurement Notes

Verify the specific suffix requirements for your design, as the 78604/3JC may differ in packaging or lead time from the -R variant. Confirm that the 6Vµs ET rating meets your circuit's voltage-time requirements. Check for end-of-life notices, as some 786 series components have been discontinued. Ensure compatibility with your PCB footprint dimensions of 9.52mm x 9.00mm.

Selection Notes

Select this component when a 2:1 turns ratio and 67µH inductance are required for surface mount pulse transformation. Consider the 6Vµs ET limit for your application's voltage and duty cycle constraints. Compare against the 78604/4MC-R if different packaging or slightly different electrical characteristics are needed. Verify that the 0°C to 70°C operating range suits your environmental conditions.

Part Context

This part belongs to the Murata 786 series of pulse transformers, which are widely used in power electronics for isolation and signal transfer. The series offers various ratios and inductance values in a compact surface mount package. The 78604/3JC specifically provides a 2:1 ratio, distinguishing it from other variants like the 1:1:1 or 1:1 models in the same family.

Replacement Considerations

Public confirmed substitute part numbers include 78604/3JC-R.
