The component has a DC resistance of 3.5 ohms and supports an isolation voltage of 2.5 kV. It utilizes PC pin leads for through-hole installation.

Feature Summary

Provides galvanic isolation with a standard 2:1:1 turns ratio
Engineered for use in switch mode power supplies and thyristor or triac firing circuits
Utilizes PC pin leads for direct printed circuit board mounting

Applications

Switch mode power supply gate drive circuits
Thyristor firing circuits
Triac firing circuits

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Production discontinuation notifications confirm that the part will be discontinued and is no longer actively manufactured. Buyers should verify current stock availability carefully, as new production units are unavailable. Sourcing may only be possible through existing inventory or secondary market channels.

Selection Notes

Select this component only if the specific 2:1:1 turns ratio and 16.3 mH inductance match the design requirements. Verify that the 2.5 kV isolation voltage meets safety standards. Due to its EOL status, alternative solutions must be evaluated for long-term supply chain stability and compatibility with existing PCB footprints.

Part Context

The 77209C belongs to the 772 series of pulse transformers from Murata Power Solutions. These components are specialized magnetic devices intended for signal transmission and isolation in power electronics. The series typically offers standardized ratios for common driver applications.
