Procurement Notes

This component has reached End-of-Life (EOL) status, with obsolescence effective February 27, 2026. Verify current stock availability through authorized distributors before finalizing designs. Ensure procurement channels are legitimate to avoid counterfeit parts during the remaining supply window.

Selection Notes

Select this part only if the specific 1:1:9 turns ratio and 230µH primary inductance match the circuit requirements. Consider the limited remaining lifespan due to EOL status when planning long-term production runs. Verify that the 6.60mm footprint fits the PCB layout constraints.

Part Context

Part of the EP6 SMD Transformer series, optimized for compact ultrasonic transducer interfaces. Manufactured by TDK Electronics under the former EPCOS brand identity. The series provides reliable isolation for high-frequency pulse signals in automotive and industrial sensing environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must identify alternative components with matching electrical specifications and mechanical dimensions independently.
