摘要： Disclosed herein is a common mode filter that includes a winding core part and first and second wires wound in a same direction around the winding core part. The first and second wires constitute a first winding block on one endmost side in an axial direction of the winding core part, a second winding block on other endmost side in the axial direction of the winding core part, and a third winding block positioned between the first and second winding blocks. The second winding block is a winding block at an odd-numbered position counted from the first winding block. The first and second wires cross each other in an area between the first and third winding blocks and in an area between the second and third winding blocks.

摘要： A dielectric fluid is provided comprising a natural bio-sourced oil and one or more compounds selected from the group consisting of phosphite compounds. It has been discovered that addition of one or more compounds selected from the group consisting of phosphite compounds to dielectric fluids comprising oil impart a stabilizing effect that reduces, inhibits or prevents formation of stray gases in the dielectric fluid during ordinary use.

摘要： An 8-shaped inductive coil device that includes a first and a second spiral coils and a connection segment structure is provided. The first spiral coil includes first metal segments and crossing connection segments disposed at a first and a second metal layers respectively and includes first connection terminals. The second spiral coil includes second connection terminals. The connection segment structure electrically couples the first and the second connection terminals. The first and the second spiral coils are disposed along an imaginary line passing through a central region of each of ranges surrounded by the first and the second spiral coils. The connection segment structure and the crossing connection segments electrically couple the part of the first metal segments substantially vertical to the imaginary line, and the connection segment structure and the crossing connection segments are disposed substantially on the imaginary line.
