| 摘要 | PURPOSE:To obtain a transformer having a low distributed capacitance and a high coupling coefficient by dividing the one coil forming conductor into two lap windings and providing other lap winding forming conductor between these two lap windings. CONSTITUTION:A primary conductor coil 2 and a secondary conductor coil 3 are buried within an integrated sintered material 1 of the ferrite having a high permeability. The secondary conductor coil 3 is divided into the portions 3', 3'' having almost equal number of truns, the diameter of windings 3', 3'' is almost equal and the winding of primary conductor coil 2 is inserted between these portions 3' and 3''. The portions 3', 3'' are mutually connected through the terminal T6 and the end portions of respective conductors are extended to the terminals T1-T5. As a method for manufacturing a laminated transformer, magnetic paste is manufactured using ferrite powder, conductor paste is manufactured using metal powder of Ag, Ag-Pd, Pd, etc. The magnetic layers 4-8 of the magnetic paste and lead conductors 9-12 for almost half-turn of conductor paste are sequentially lapped by printing method in this sequence in order to obtain a laminated transformer. | ||||||
