[0002] A capacitor is a passive electronic component that can store and release electrical energy. It consists of two adjacent conductive plates and an insulating medium in between. Its core characteristic is to hold electric charge. It is an indispensable component in electronic and power systems and is often used in power circuits, signal processing, and high-frequency circuits.

[0003] The existing application publication number CN118782386A discloses a capacitor with adjustable capacity, comprising: a capacitor housing; a marking component is fixedly arranged on one side of the capacitor housing, and a control structure is fixedly arranged on the other side of the capacitor housing; an automatic exhaust structure is fixedly arranged inside the top side of the capacitor housing, and an automatic air intake structure is arranged inside the automatic exhaust structure;

[0004] However, it still has the following disadvantages in actual use:

The capacitor is connected to the circuit through the electrode column A and the electrode column B. However, when in use, the lengths of the electrode column A and the electrode column B are fixed. If the electrode column A and the electrode column B are too long, the parasitic inductance and resistance will increase, affecting the high-frequency performance or causing voltage drop. If the electrode column A and the electrode column B are too short, it is not convenient to connect them to the circuit.

[0006] In the above-mentioned capacitor, a conductive plate A is fixedly arranged in a straight line on the inner side of the capacitor shell, an electrode column A is fixedly arranged inside the conductive plate A, and a fixed electrode piece is fixedly arranged on the outer side of the conductive plate A, a conductive plate B is fixedly arranged inside the capacitor shell, and the outer side of the conductive plate B is in contact with the outer side of the moving electrode piece. The fixed electrode piece, the moving electrode piece and the electrolyte filled in the capacitor shell are used to store the charge. However, when in use, the electrolyte in the capacitor shell will be consumed due to various reasons, which makes it inconvenient to automatically replenish the electrolyte, thereby affecting the use of the capacitor.

[0007] To this end, we provide a capacitor with conveniently adjustable compensation capacity to solve the above problems. Utility Model Content
