Patent ID: 11424066

Abstract:
An electronic component 100 includes: a circuit board module 104 which is composed of a plurality of layers, and in which a primary circuit 120 and secondary circuits 122, 124 are each formed using wring patterns of a first layer L1 to an eighth layer L8; and a magnetic core 106 which magnetically couples the primary circuit 120 and the secondary circuits 122, 124. The circuit board module 104 includes: a primary winding 120b and secondary windings 122b, 124b which are formed spirally around the magnetic core 106; and a third layer L3 and a sixth layer L6 interposed between a fourth layer L4 of the primary winding 120b and a second layer L2 of the secondary winding 122b and between a fifth layer L5 of the primary winding 120b and a seventh layer L7 of the secondary winding 124b.
