Description

Technical Field

[0001] The invention relates to the technical field of capacitors, in particular to a three-core parallel capacitor. Background Art

[0002] Capacitors are electrical components that store electric charge. There are many types of capacitors on the market, which can be roughly divided into several categories such as ceramic, electrolytic, and film. Among them, film capacitors are widely used in analog circuits because of their advantages such as non-polarity, high insulation impedance, excellent frequency characteristics, and low dielectric loss. Especially in the signal interconnection part, capacitors with good frequency characteristics and extremely low dielectric loss must be used to ensure that the signal will not be distorted too much during transmission.

[0003] At present, aluminum can capacitors are mainly composed of aluminum shells, cores, pole strips, electrode terminals and fillers. The aluminum can capacitors in the transfer mode are a certain number of cores connected in different ways through pole strips, and then led out by terminals. The electrode terminals are fixed on the top of the plastic cover, and the plastic cover is assembled with the aluminum shell, and then the fillers are poured into the aluminum shell.

[0004] Capacitors usually generate heat when powered on, which includes heat generated by the leads and the product itself. Generally, in parallel capacitors, each core is very close to the other, but the conventional parallel connection method results in different numbers of pole strips on the outside of each core, and the pole strips themselves generate heat, resulting in different heat generation of the three cores and their outsides, leading to different heat dissipation environments inside the capacitor, making the temperature of the upper core higher, making it difficult to exert the performance of the capacitor and reducing the service life of the capacitor.
