Procurement Notes

Verify that the specific application requires PoE capability, as this model is optimized for Power over Ethernet standards. Confirm that the system design accommodates the 48-pin SMD-48 package dimensions and the open header configuration. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check compatibility with 100 Base-T network speeds, as this transformer is not rated for higher Gigabit speeds. Validate that the 1500 Vac isolation rating meets safety requirements for the target equipment class.
