Switching Converter, SMPS Transformers Procurement Notes

Verify the specific suffix NLT against the manufacturer's current datasheet to confirm packaging type and availability status. Ensure the selected variant matches the required isolation voltage and frequency specifications for the target application. Cross-reference the Mouser and DigiKey part numbers to confirm identical component specifications before finalizing procurement orders.

Switching Converter, SMPS Transformers Selection Notes

Select this component for designs requiring high isolation voltage and operation at 200kHz. The 14.50mm x 17.65mm footprint must be accommodated within the PCB layout constraints. Consider the auxiliary winding capability if gate drive or feedback power is needed directly from the transformer. Verify thermal performance under maximum load conditions given the 130°C operating temperature limit.
