78613/9MC

Overview

The Murata Power Solutions 78613/9MC is a pulse transformer designed for surface mount applications. It features a 1CT:1 turns ratio and an inductance of 10,000 µH with a voltage-time product (ET) of 56 V/µs. The component measures 9.52 mm in length, 9 mm in width, and 6.35 mm in height. It operates within a temperature range of 0°C to +70°C and complies with RoHS standards.

Feature Summary

• Surface mount construction for automated PCB assembly
• Center-tapped primary winding configuration
• High inductance capability for energy storage applications

Applications

• Flyback converter transformer stages
• Isolated DC-DC converter designs
• Pulse coupling circuits requiring center tap

Procurement Notes

Verify the specific suffix designation carefully, as the 78613/9C variant is documented as End-of-Life. Confirm current availability status directly with authorized distributors or Murata Power Solutions before finalizing procurement plans to ensure supply continuity.

Selection Notes

Select this component when a surface mount footprint is required alongside a center-tapped primary winding. Ensure the 56 V/µs ET rating and 10,000 µH inductance align with the circuit's magnetic requirements and thermal operating limits.

Part Context

This part belongs to the Murata 786 series of general-purpose pulse transformers. These components are engineered for compact power electronics, offering reliable isolation and signal transfer in space-constrained industrial and consumer electronic designs.

Replacement Considerations

Consult official documentation for suggested alternates. The 78613/9C through-hole version is obsolete; verify if the 78613/9JC-R surface mount variant serves as a functional substitute.
