The Iron-base nanocrystalline  are composed of iron, silicon, boron and small amounts of copper, molybdenum, niobium, etc., of which copper and niobium are essential elements for living nanocrystalline structures. They were first fabricated into amorphous ribbons, which were then appropriately annealed to form a mixture of micro-crystalline and amorphous structures.Such material is not o...

With the successful development of a planar core, a planar transformer design was realized. The planar transformer requires a magnetic core, and the winding is a planar structure, usually chopped into PCB windings to achieve high frequency and low shape. In the market, the Planar transformers power from 5W to 20KW, frequency from 20KHz to 2MHz, efficiency up to 98%. It’s widely application in tele...

The planar transformer is special designed for low profile & low loss but high power application. Compared with traditional toroidal transformer, laminated core transformer, etc., the planar transformer can be through-hole mounted to the board, or can be integrated into PCB directly , thus the low-profile transformer that could handle a range of current values work. A PCB with traces...
