78604/8C

Overview

The Murata Power Solutions Inc. 78604/8C is a general-purpose pulse transformer with a turns ratio of 2:1 and an inductance of 1000µH (1mH). It features an Et rating of 15 Vµs and operates within a temperature range of 0°C to +70°C. The component utilizes a through-hole DIP mounting style, measuring 9.52 mm in length, 9 mm in width, and 6.35 mm in height.

Feature Summary

• Provides electrical isolation for signal transmission in switching applications
• Supports high-speed pulse propagation with defined voltage-time characteristics
• Designed for reliable operation across standard industrial temperature ranges

Applications

• Gate drive circuits for power switches
• Isolated communication interfaces
• Pulse transformer coupling in power supplies

Procurement Notes

Verify the specific suffix 'C' indicates through-hole packaging distinct from surface-mount variants like 'JC'. Confirm RoHS3 compliance status and check for recent Product Change Notifications regarding manufacturing site updates or material substitutions before finalizing procurement orders.

Selection Notes

Select this component when a 2:1 turns ratio and 1mH inductance are required for through-hole assembly. Ensure the 15 Vµs Et rating meets the system's voltage-time requirements. Compare against SMT alternatives if board space constraints necessitate surface-mount technology.

Part Context

This part belongs to the 786 series of pulse transformers from Murata Power Solutions. The series offers various inductance values and mounting styles, including both through-hole and surface-mount options, designed for general-purpose isolation tasks in electronic circuits.

Replacement Considerations

Direct parameter-equivalent substitutes include the 78604/8JC for surface-mount applications, though package differences require layout adjustments. Verify pinout compatibility and mechanical dimensions when considering cross-references.
