Triad Magnetics has been an industry leading transformer manufacturer for over 70 years. Among our extensive selection of high-powered, highly reliable, and compact transformers is our line of more than 50 PC Mount Flat Pack™ power transformers.

Designed to meet the low clearance space requirements of PC board and solid state power designs, as well as for control and instrumentation applications, our Flat Pack™ transformers feature mounting widths that range from 1.26 in to as small as 0.88 in, and mounting lengths from 2.52 in to as short as 1.62 in. Card spacing ranges from ¾ in to 1 ½ in, allowing for electrical ratings between 2.5 VA and 48 VA.

Available in a dual primary and dual secondary configuration, which allows for both in series and parallel linking, PC Mount Flat Pack™ power transformers are designed to operate at the voltage and current levels most commonly used in electronics power applications.

The specification table below has information for all PC Mount Flack Pack™ power transformers, and you can contact Triad Magnetics at any time to discuss your application and requirements in detail.
