Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm that the 1CT:1 configuration matches the circuit requirements, as other variants in the 78613 series offer different ratios or leaded packages. Check current status as components may be subject to change notifications.

Selection Notes

Select this part for applications requiring a center-tapped primary with high inductance in a compact SMD footprint. Ensure the operating temperature range of 0°C to +70°C aligns with the system environment. Compare against through-hole alternatives if mechanical stress resistance is critical.

Part Context

This component belongs to the Murata 786 series of general-purpose pulse transformers. The series offers various winding configurations including standard and center-tapped options in both surface mount and through-hole packages. It is designed for reliable performance in industrial and commercial power supply applications.

Replacement Considerations

Public confirmed substitute: 78613/8C (Through-hole, 1CT:1, 1mH). Note that 78613/8C is a through-hole variant with different inductance and packaging compared to the SMD 78613/4MC-R.
