PC board plug-in mounting
Double reinforced insulation
Dual bobbin; high (4000V) primary to
secondary isolation
Non-concentric design - eliminates ESS and
reduces primary to secondary capacitance
No crossover between primary/secondary leads
Vacuum impregnated - withstands board washing
systems and reduces audible noise
Baked resin provides an environmentally-
resistant finish
