Laminated transformers
overview
With the addition of era’s encapsulated 50/60Hz transformers to the existing line of Pulse open frame transformers, Pulse now offers a complete
line of laminated transformers for all your low power, linear transformer needs. With power ratings from 0.08VA to 175VA, fully encapsulated
transformers, split bobbin designs, and a wide variety of domestic and international agency approvals, Pulse is truly the one stop shop for all
your 50/60Hz needs.
Advantages of Encapsulated Transformers:
l
Better heat dissipation achieved through vacuum encapsulation, resulting in more output power from a smaller, more compact design.
l
Vacuum encapsulation provides protection against external influences (e.g. wash operations) and mechanical stress (e.g. vibration). It also
reduces the potential of noise through vibration.
l
Dimensional accuracy of each transformer guaranteed by stable and controlled manufacturing processes, allowing for automatic pick and
place operations.
This catalog serves as an overview for the Pulse Laminated Transformer product line. Please contact Pulse Power Applications Engineering for
more information. For Pulse´s complete line of Power Inductors, Transformers, Chokes and Current Sense Magnetics, please see the Switching
Power Magnetics catalog.

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
