A low-core-loss transformer for high transfer ratio and high power density applications can have five pillars including four corner pillars and at least one center pillar between magnetic metal plates. The center pillar provides an additional flux path to reduce thermal and core losses and improve efficiency. Magnetic flux density may be further reduced by having multiple central pillars in an N-track configuration in several kinds of symmetrical arrangements. The low-core-loss transformer achieves a flexible voltage transfer ratio. The ratio can be either even or odd numbers. An odd ratio design is able to fulfill the requirement of future data centers to supply a 400-volt high-distribution power bus. The transformer windings can be traces on a Printed Circuit Board (PCB) that integrate electronic components for a compact and modular design.

A multilayer triplexer includes a first coil connected between a common terminal and a first filter, a second coil connected between the common terminal and a second filter, and a third coil connected between the common terminal and the third filter. The first coil, the second coil, and the third coil each include a coil conductor pattern between ones of substrate layers of a multilayer body. The coil conductor pattern of the first coil, the coil conductor pattern of the second coil, and the coil conductor pattern of the third coil do not overlap each other when the multilayer body is seen through in a direction in which the substrate layers are stacked on one another.

A wireless device is provided and includes a first coil and at least one conductive assembly. The first coil includes a first metal wire and a second metal wire. The first metal wire is disposed on a first plane and has a first spiral structure. The second metal wire is disposed on a second plane and has a second spiral structure, and the second metal wire is electrically connected to the first metal wire. The conductive assembly has at least one metal connector. The conductive assembly is disposed on an innermost turn of the first spiral structure and an innermost turn of the second spiral structure.

An electronic component includes a wire winding wound around a central axis. The wire winding having first and second ends, and first and second terminals are connected to or formed by the first and second ends. The terminals provide electrical contacts for connecting the component into a circuit. The component has a wet press molded body made of a mixture of magnetic and non-magnetic material that is heated and pressed about the wire winding. The wet press molded body leaves at least a portion of the terminals exposed for mounting the component to the circuit.

An electronic component includes a member with marking having at least one marking area to be processed digitally, as well as a member other than the member with marking. The marking allows for tracing the production history of individual electronic components.
