78601/8MC-R

Overview

The Murata Power Solutions Inc. 78601/8MC-R is a surface-mount pulse transformer designed for general-purpose applications within the 786 series. It features a 1:1 turns ratio and an inductance of 1 mH. The component has a voltage-time product (ET) rating of 15 V/us and operates within a temperature range of 0°C to 70°C. Its physical dimensions are 9.52 mm in length, 9.00 mm in width, and a maximum height of 6.35 mm. The device is RoHS compliant and packaged in cut tape or reel formats.

Feature Summary

• Surface-mount construction for automated PCB assembly
• General-purpose isolation capability
• RoHS compliant manufacturing

Applications

• Signal isolation in digital communication interfaces
• Pulse transmission in isolated power supply circuits
• Common-mode filtering in data lines

Procurement Notes

Verify that the specific suffix 'MC' matches the required package variant, as other suffixes may denote different mechanical footprints. Confirm that the 15 V/us ET rating meets the peak voltage requirements of the target circuit. Ensure the operating temperature range of 0°C to 70°C is sufficient for the intended environment. Check for the Not Recommended for New Design status if starting a new project.

Selection Notes

Select this component when a 1:1 isolation ratio and 1 mH inductance are required for surface-mount designs. Compare the 15 V/us ET rating against the signal amplitude and duration to ensure no saturation occurs. Consider the 78601/8JC-R as a potential alternative if the MC package is unavailable or if a different package option is preferred within the same electrical family.
