a circuit element

Abstract

The invention discloses a circuit element. The circuit element comprises ferrite base plates in even number laminated sequentially from upside to downside, an outer input terminal electrode, an outer output terminal electrode and an outer grounded terminal electrode; each ferrite base plate is provided with a conductor block, a wire and an electric connecting terminal; the wires on all the ferrite base plates are electrically connected in sequence through electric connecting terminals to form a conductive coil; one end of the conductive coil is electrically connected with the outer input terminal electrode while the other end of the conductive coil is electrically connected with the outer output terminal electrode; the conductor blocks of the ferrite base plates at the odd-number positions are electrically connected with the outer input terminal electrode, and the conductor blocks of the ferrite base plates at the even-number positions are electrically connected with the outer grounded terminal electrode; or the conductor blocks of the ferrite base plates at the odd-number positions are electrically connected with the outer grounded terminal electrode, and the conductor blocks of the ferrite base plates at the even-number positions are electrically connected with the outer input terminal electrode. According to the embodiment of the invention, the circuit element can integrate a magnetic ball and a capacitor into a structure.

Description

technical field [0001] The invention relates to the technical field of circuit elements, in particular to a circuit element. Background technique [0002] In circuit design, the quality of the circuit design seriously affects the performance of the entire circuit. figure 1 It is a schematic diagram of the part between the power supply and the device in the prior art circuit design. Such as figure 1 As shown, in all circuit designs, the system (system) generally provides external power for the device, but the external power provided by the system has certain instability, which may cause large current and high voltage. The device is seriously affected by being burned under high current and high voltage, generally a fuse (fuse) component 11 is installed between the power supply and the device; in addition, the power supply provided by the system will carry a certain amount of noise, which will enter the PCB (Printed Circuit Board, printed circuit board) affects EMI (Electro ...
