Toroidal transformers are passive electronic components, made by circular ring or donut shaped magnetic core of ferromagnetic materials, and then wire wound acroundly.
Comparing traditional laminated transformers, toroidal transformer provides lower leakage flux, higher efficiency,  a more compact size, less audible vibrations & hum, radiates less electromagnetic interference (EMI).
OEM servise are warmly welcome. Sample Quantity supportted. Project Design Supported.
Toroidal transformers popular in electrical equipment, such as TVs, radios, computers, and audio systems, for power suppliers, inverters, and amplifiers.
