Abstract
A current breaker comprises a multi-layer printed circuit board (PCB), a ground plane, a metal component and a conductive via hole. The ground plane is disposed in a first metal layer of the multi-layer PCB and comprises a slot forming inductive impedance. The slot comprises an extended portion. The metal component is disposed in a second metal layer of the multi-layer PCB. Capacitive impedance is formed between the metal component and the ground plane. The projection of the metal component on the ground plane and the extended portion of the slot partially overlap. The conductive via hole penetrates the multi-layer PCB to connect metal component with the ground plane. The first and the second metal layers are any two metal layers of the multi-layer PCB. The inductive impedance formed by the slot and the capacitive impedance formed between the metal component and the ground plane create a parallel LC equivalent circuit.
