78615/9C

Overview

The Murata Power Solutions 78615/9C is a general-purpose pulse transformer designed for through-hole mounting. It features a 1:1 turns ratio and an inductance of 10,000 µH (10 mH). The component has a voltage-time product (Et) rating of 56 V/µs. Physical dimensions are 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.

Feature Summary

• Provides galvanic isolation with a 1:1 turns ratio for signal transmission.
• Engineered for high voltage-time product capability to handle demanding pulse widths.
• Constructed for reliable through-hole PCB integration.

Applications

• Gate drive circuits for power switching devices
• Isolated digital communication interfaces
• Pulse generation and shaping networks

Procurement Notes

Verify the specific suffix 'C' against official Murata documentation to confirm pinout and electrical tolerances. Confirm RoHS compliance status via the current datasheet. Check for obsolescence notices as lifecycle status may vary by region. Ensure the through-hole package fits the target PCB footprint before ordering.

Selection Notes

Select this component when a 1:1 isolation ratio and 10 mH primary inductance are required. The 56 V/µs Et rating determines the maximum pulse width at a given voltage. Compare physical dimensions against available board space. Verify that the operating temperature range meets the environmental requirements of the final assembly.

Part Context

This part belongs to the Murata 786 series of general-purpose pulse transformers. These components are typically used in industrial and commercial electronics where signal integrity and isolation are critical. The series offers various inductance and Et ratings to suit different circuit timing requirements.

Replacement Considerations

Murata suggests the 78615/9JC as an alternate option. Verify if the 'J' suffix indicates a different tolerance or packaging configuration compared to the 'C' variant before substitution.
