POE300F-24LD Frequently Asked Questions (FAQs)

Coilcraft recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a microstrip layout for the primary and secondary windings to minimize electromagnetic interference (EMI).
Ensure that the component is soldered correctly, and that the PCB is designed to minimize thermal stress. Also, consider using a thermally conductive material for the PCB substrate to help dissipate heat.
The maximum allowable voltage stress is 1500Vrms for the primary winding and 1000Vrms for the secondary winding. Exceeding these values may cause insulation breakdown or other damage.
Yes, the POE300F-24LD is designed to meet the requirements of IEEE 802.3bt Type 3 (Class 4) PoE, which supports up to 25.5W of power delivery.
Follow good EMC design practices, such as using a shielded enclosure, minimizing loop areas, and using filtering components as needed. Also, ensure that the transformer is properly grounded and that the PCB layout is optimized for EMI reduction.
