Switching Converter, SMPS Transformers Procurement Notes

Verify the specific datasheet version before integration, as manufacturer documentation may undergo revisions. Confirm that the through-hole mounting style aligns with your PCB layout constraints. Ensure the 70kHz operating frequency matches your system's electromagnetic interference filtering strategy. Cross-reference the LT3799 compatibility notes to validate control loop stability within your specific application parameters.

Switching Converter, SMPS Transformers Selection Notes

Select this component when designing offline flyback converters requiring high isolation voltages and through-hole assembly. The ER28/14 core size indicates suitability for higher power levels compared to smaller surface-mount alternatives. Consider the 70kHz frequency constraint when designing magnetics and filters. Verify thermal management needs given the 80W power handling context associated with this core format.

Switching Converter, SMPS Transformers Part Context

This part belongs to Würth Elektronik's MID-OLLT series of offline flyback transformers. These components are distinct from their surface-mount MID-FLYADI or MID-IBTI lines by their through-hole construction and larger ER28/14 core footprint. The series targets industrial and consumer applications needing robust isolation and compatibility with standard offline controller ICs like the LT3799.

Switching Converter, SMPS Transformers Replacement Considerations

Direct substitutes must match the ER28/14 core geometry, 1500Vrms isolation rating, and 70kHz operational frequency. Verify pinout compatibility and winding ratios against the original design specifications. Consult manufacturer PCNs for any material or process changes that might affect mechanical fit or electrical performance.
