PoE FLYBACK

Production Information
 
ER18 | ER20 | EPC16 | Z18 Planar Transformer
Flyback Topology -- CCM + BCM Options. Low Profile [7.0 to 8.5mm].
Highest Efficiency - -Secondary Side Synchronous FET Driven.
Aggressive Interleave planar construction -- lowest achievable Leakage Inductance. 
Multilayer PCB optimization for lowest AC resistance and Proximity Effect.
Wide variety of PNs, Designs and Turns Ratios in stock [Contcat Us]
Surface Mount, Thru-Hole, Pad-to-Pad Options
