An ultra-high voltage leaded capacitor and its preparation method

Abstract

The invention discloses an ultra-high voltage leaded capacitor and a preparation method thereof, comprising an aluminum shell, a core pack, a rubber plug, and a lead wire, the lead wire is fixedly connected to the core pack, and the rubber plug is arranged close to the electrode. The end of the core package, the lead wire, the rubber plug and the core package are arranged in the aluminum shell sequentially from top to bottom, the core package includes aluminum foil and electrolytic paper, and the core package The aluminum foil and the electrolytic paper are laminated and wound together, and the core package is also impregnated with an electrolyte, the electrolyte includes a solute, a solvent and an additive, and the weight ratio of the solute is 15% ~25%, the weight ratio of the solvent is 60%~70%, the weight ratio of the additive is 5%~15%, and has the advantages of rated voltage reaching 600V and stable operation.

Description

Technical field [0001] The present invention relates to the field of capacitors, and more particularly to an ultra high pressure lead capacitor and a preparation method. Background technique [0002] The capacitor is one of the three major electronic passive components, which is an indispensable infrastructure in the electronic circuit, accounting for 40% of the total amount of electronic components, and the capacitor is also referred to as a capacitor. It is a component that can store a certain amount of charge, extensive Applied in the circuit in the circuit, coupling, bypass, filtering, etc. [0003] The applications of capacitors include military and civilian use, in which civilian market is divided into civil industrial markets and civil consumption markets. Capacitors have applications in weapons and equipment such as waves in military fields, including system communication equipment, industrial control equipment, medical electronic equipment, rail transit, precision instru...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the production materials such as electrolyte ratio technology and related capacitor parts matching are immature, so that the rated voltage of a capacitor with an operating temperature of 105°C cannot reach 600V, thereby providing a leaded ultra-high voltage capacitor and its preparation method , the ultra-high voltage capacitor includes an aluminum shell, a core pack, a rubber plug, and a lead wire, the lead wire is fixedly connected to the core pack, and the rubber plug is arranged at the end of the lead wire close to the core pack, The lead-out wire, the rubber plug and the core pack are arranged in the aluminum shell sequentially from top to bottom,
