Abstract

The invention discloses an ultrahigh-voltage lead capacitor and a preparation method. The ultrahigh-voltage lead capacitor includes an aluminum shell, a core pack, a rubber plug and a lead-out wire. The lead-out wire is fixedly connected with the core pack. The rubber plug is arranged at the end of an electrode near the core pack. The lead-out wire, the rubber plug and the core pack are arranged in the aluminum shell in turn from top to bottom. The core pack includes aluminum foil and electrolytic paper. The core pack is formed by laminating and winding the aluminum foil and the electrolytic paper. The core pack is also impregnated in electrolyte. The electrolyte includes solute, solvent and additive, wherein the weight percent of the solute is 15-25%, the weight percent of the solvent is60-70%, and the weight ratio of the additive is 5-15%. The ultrahigh-voltage lead capacitor has the advantages such as rated voltage of up to 600V and stable work.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to an ultra-high voltage lead type capacitor and a preparation method. Background technique [0002] Capacitor is one of the three major electronic passive components. It is an indispensable basic component in electronic circuits, accounting for about 40% of all electronic components. Capacitors, also known as capacitors, are components that can store a certain amount of charge. It is used in DC blocking, coupling, bypass, filtering and other aspects in the circuit. [0003] The application fields of capacitors include military and civilian use, among which the civilian market is further divided into the civilian industrial market and the civilian consumer market. Capacitors are used in ship aviation, aerospace, weapons, electronic countermeasure weapons and other weapons and equipment in the military field. Civilian industries include system communication equipment, industrial control eq...
