Description
Technical Field
The utility model relates to a film capacitor of light weight.
Background
In the field of power electronics, a non-standard thin film capacitor in the traditional sense generally adopts alloy aluminum or Sus304 stainless steel as a shell customization of materials, the BOM cost of the customized capacitor is increased while the installation size requirement is met, and meanwhile, the shell of the capacitor is made of metal materials, so that the requirement of the insulating installation distance is greatly increased, and the BOM cost is increased in order to meet the electrical requirement. Finally, because the density of stainless steel and aluminum alloy is higher than that of the existing epoxy, the actual weight of the product is greatly increased.
Light weight thin film capacitors with an epoxy material as the housing have special significance for their application.
In some moving carriers, such as subway, rail transit, automobile and other industries, design engineers have strict requirements on the overall weight, so that the power devices are separated one by one and comprise customized thin film capacitors. Traditionally meaningful designs, while meeting performance requirements, are typically higher than customer requirements due to their weight. Compared with the traditional capacitor, the novel thin-film capacitor with the light-weight epoxy shell has the advantages that the weight is reduced by about 20-30% under the condition that the performance is simultaneously met, and the special requirements of customers are met on the premise that the BOM cost is not increased.
