EFD20 core configuration
NPB winding technology

Applications

Board mount power transformer applications
Forward converter circuits
High-frequency power supply designs

Procurement Notes

Verify the specific datasheet version and RoHS compliance status before procurement, as availability information varies across distributors. Confirm that the 12-terminal package matches the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized channels to avoid counterfeit components.

Selection Notes

Select this component when a 57.6 µH inductance is required for forward converter topologies using EFD20 cores. The 34.5W power rating defines the thermal and electrical limits for the design. Consider the 12-terminal layout for routing complexity. The wide temperature range supports operation in demanding industrial environments without derating adjustments.

Part Context

This part belongs to the Pulse Electronics high-frequency wire wound transformer series. It is distinct from general-purpose audio or signal transformers due to its specific power handling capabilities. The EFD20 form factor provides a balance between magnetic efficiency and physical size for surface mount implementations.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative manufacturers.
