78613/1C

Overview

The Murata Power Solutions 78613/1C is a general-purpose pulse transformer designed for through-hole mounting. It features a 1CT:1 turns ratio and a primary inductance of 2000 µH. The component supports a voltage-time product (Et) of 20 Vµs and provides 1 kV isolation voltage. 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 kV rating between windings
• Features a center-tapped primary winding configuration
• Designed for low-profile surface or through-hole PCB integration

Applications

• Gate drive circuits for power semiconductors
• Pulse isolation in digital communication interfaces
• Signal coupling in isolated power supply feedback loops

Procurement Notes

Verify the specific suffix '1C' against official Murata documentation to confirm the exact electrical parameters, as variations exist within the 786 series. Confirm RoHS compliance status directly from the manufacturer's current datasheet. Ensure the through-hole DIP package aligns with the target PCB footprint and assembly capabilities. Check for any recent Product Change Notifications that may affect pinout or material composition.

Selection Notes

Select this component when a 1CT:1 ratio and 2000 µH primary inductance are required for signal transmission. The 20 Vµs voltage-time rating determines the maximum pulse width capability at given voltages. Consider the 0.63 ohm DC resistance for loss calculations. The 1 kV isolation voltage defines the safety barrier requirements. Compare physical dimensions against available board space constraints.
