Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before integration. Confirm that the through-hole package dimensions align with the target PCB footprint. Ensure the operating frequency range matches the system's switching requirements to maintain optimal performance and isolation integrity.
Selection Notes
Select this component when designing systems requiring integrated PoE power delivery with high isolation voltage. The 1875Vrms rating suits applications demanding robust electrical separation. Consider the 250kHz operating frequency for compatibility with standard SMPS controllers. Verify thermal management needs based on the intended power load and ambient conditions.
