The invention discloses a cascaded structure capacitor core. The cascaded structure capacitor core comprises an aluminum foil, a metallization polypropylene film and a dielectric layer. The core is formed by winding the aluminum foil and the dielectric layer. The metallization polypropylene film winds the dielectric layer in sequence, the two ends of the aluminum foil extend outwards, and the middle of the aluminum foil is hollow. The cascaded structure capacitor core overcomes the defects in the prior art, and is simple in design and reasonable in structure. The capacitor core has high-pressure resistant performance and large-current resistant performance and is small in size and suitable for an electronic rectifier.
Description
[0001] technical field [0002] The invention relates to the technical field of capacitors, in particular to a capacitor core with a series structure. [0003] Background technique [0004] Existing high-voltage aluminum foil film capacitors are generally large in size, and the distance between capacitor leads is more than 15mm, which limits the applicable occasions. Film capacitors with smaller structures are generally not resistant to high pulses, are not suitable for high-current circuits, and have a short life when applicable. [0005] Contents of the invention [0006] The object of the present invention is to provide a series structure capacitor core, which overcomes the shortcomings of the prior art, has a simple design and a reasonable structure, and the capacitor core has strong high voltage resistance, high current resistance and small volume and is suitable for electronic rectifiers. [0007] The technical scheme that the present invention adopts is as follow...
