Production information
80R2 | 80R4 | 80R6 Series Planar Transformer

Forward Active Clamp Topology  
Highest Efficiency attributable to Planar Design. 
Aggressive Interleave by design results in lowest achievable Leakage Inductance.
Multilayer PCB optimization for lowest AC resistance and Proximity Effect . 
Wide variety of Turns Ratios in stock but not shown in Table.
