Procurement Notes

Verify the specific manufacturer part number against official TDK documentation to ensure correct variant selection. Confirm that the required inductance and isolation characteristics match the design specifications. Check for any updated environmental compliance declarations or REACH status changes prior to final procurement approval.

Selection Notes

Select this component when a compact surface mount solution for gate drive isolation is required. Ensure the circuit design accommodates the 350µH inductance and 1:1 turns ratio constraints. Verify that the PCB footprint matches the 6.70mm x 6.10mm package dimensions and that thermal management supports the specified operating temperature range.

Part Context

This component belongs to the TDK EP5 series of SMT gate drive transformers. These devices are engineered for reliable performance in demanding power conversion environments. The series offers various inductance options while maintaining consistent physical footprints to facilitate design flexibility across different product generations.

Replacement Considerations

Consult official TDK substitution guides for verified alternatives. Cross-reference electrical parameters such as inductance, turns ratio, and package dimensions to ensure compatibility.
