Description

technical field

[0001] The present invention relates to a ceramic co-fired common-mode filter and a manufacturing method thereof, in particular to a method of using different electrical properties of different materials to select suitable materials for different parts of the element according to electrical requirements, and to Different materials are prepared according to the powder characteristics of the material, so that they are produced together in each process, and then the ceramic co-fired common mode filter and its main body are completed by co-firing through the researched special sintering curve. Production Method. Background technique

[0002] There are two main types of common-mode filters in the prior art, which are laminated and wire-wound. Wire-wound filters have better electrical properties, but their cost is high and their output is small, so they cannot be widely used in electronic products. application. And the multilayer common mode filter 10 (as shown i...
