Fast combination of common-mode filters

Abstract

This invention provides a rapidly combinable common-mode filter, comprising: a first substrate; a first inductor group disposed on the first substrate, the first inductor group having a first bonding portion and a second bonding portion; and a second inductor group disposed on the first substrate, the second inductor group having a first bonding portion and a second bonding portion. By mutually supplementing each other, the first bonding portion of the first inductor group and the first bonding portion of the second inductor group, and the second bonding portion of the first inductor group and the second bonding portion of the second inductor group, the inductor group can be expanded according to user needs, or the coils can be quickly replaced, or flanges or center posts of different materials can be replaced, thereby changing the applicable frequency. This allows for widespread use, effectively reduces production costs, and minimizes resource waste.
