Procurement Notes

Verify the specific ordering suffix (TR, TRL, TRR, or none) to confirm packaging orientation and quantity. Confirm lead-free status if required by assembly specifications. Ensure thermal management aligns with the specified junction-to-case thermal resistance values during design integration.

Selection Notes

Select this component for applications requiring a compact surface mount solution with high surge current handling. The center tap topology simplifies circuit design for specific converter topologies. Evaluate thermal constraints against the maximum allowable case temperature curves to ensure reliable operation under varying duty cycles.
