SMPS Transformers

Mn Zn cores with very low power loss are used in the design of pulse transformers, optimally matching the core type to specific applications and operating frequency. Power transmission ranges from 1 W to 1 kW. We manufacture transformers using toroidal cores or other shapes, such as: EE, EFD, ETD, RM, etc. We have different bobbins available for each type of core, having different number and pattern of pins as well as different numbers of sections of bobbin. For each type of core we have components on stock, which enable us to put together a pair of cores of practically any air gap size. Each time our customers consult us, we try to offer an optimal circuit solution for reasonable price based on our best experience. We do not charge any additional fees for our switching-mode power supplies designs, providing our client with the entire set of inductive components. In our transformer's manufacturing process we use enamel insulated or cotton insulated wire, twisted wires, litz wires or special triple insulated wires of diameters of 0.1 to 0.6mm, which enable us to build the very low power transformers, where due to the miniature sizes it is not possible to use safety margins, while it is necessary to maintain high resistance to electric breakdown. The special glues are used for mating faces of cores. These glues are resistant to mechanical forces and to high temperatures. If required, we use the magnetic shields as well as vacuum impregnation. Our components are successful in many areas of electronics and other trades of industry; both as the EMC components and as the components in power supply systems, telecommunication systems, military technology, mining, automation and metrology.
