Products include transformers, inductors, reactors, capacitors and power supplies. The transformer group includes power (single or multi-phase), audio, saturable, and encapsulated high-voltage designs. Inductors and reactors are the power, audio, and saturable types. Ratings rarely exceed 5kVA. The orientation is principally for military (MIL-PRF-27) or space flight operations (MIL-STD-981). Most available core types and materials, including ferrites toroids, C-cores, and laminations are used. Materials used for winding coils include copper foil for high current applications and heavy gauge to ultra-fine copper wire. Roughly two-thirds of the units produced weigh less than a pound.





 

Magnetics are highly labor intensive. On the job training is performed continuously by experienced and highly skilled group leaders with a high degree of engineering and management oversight.
 

 



A well equipped staff of technicians perform electrical characteristics tests to evaluate units prior to shipment as well as at critical points during production. The test department also performs most of the environmental and qualification tests of MIL-PRF-27 & MIL-STD-981.
 

 



 
Precision layer winding requires accurate control of wire tension and the proper placement of windings. This is essential in constructing coils that provide optimal electrical ratings and the smallest physical dimensions possible.
