Technical development trend of aluminum electrolytic capacitors
With the continuous development of the manufacturing technology of electrolytic capacitors, the cost of equipment manufacturing and the cost
of materials are declining, and the point-solving capacitors have become a generally optimistic quality for manufacturers, and their future developments are generally following the following trends.
Volume reduction and flattening In recent years, with the increasing capacity of the capacitor aluminum foil, the volume of the electrolytic capacitor has been reduced, and the cost reduction has created the necessary conditions. The foil strength is increased and the tail capacitor is flattened and the whole machine is completed. Thin words create conditions. The development trend of aluminum foil with high strength and high specific volume point solution also causes the capacitor volume to shrink and flatten.
Low impedance, ripple current, long life
The development of high conductivity materials and ionic liquids has contributed to the continuous improvement of the conductivity of electrolytes. The density and impedance of new type of capacitors for capacitors are also decreasing. The development of high temperature sealing materials for capacitors is the low impedance and high resistance of capacitors. Ripple, long-life performance is greatly improved. In the high temperature working environment, the 10,000-hour capacitor product also appears accordingly.
The service life of the upper limit working temperature is continuously improved
With the development of automotive electronics, the life of capacitors with an upper limit of 125 °C is rapidly increased from 1000 to 2000 h to 3000 to 5000 h, the upper limit operating temperature is 150 ° C, and the aluminum electrolytic capacitors with a life of 1000 to 2000 h are also mass-produced, with the automotive industry. With continuous development, the service life of the upper limit operating temperature of the capacitor will further develop.
Commercialization of solid electrolytic capacitors is rapidly increasing
Because solid electrolytic capacitors are more suitable for extreme operating temperatures than conventional aluminum electrolytic capacitors, the risk of failure on the board is greatly reduced. Solid capacitors are also more suitable for high-tech, high-precision electronics. However, since the cost of solid capacitors is much higher than that of point capacitors, it is seriously hindered from commercialization. However, with the continuous development of this time, the continuous innovation of production technology has led to the continuous reduction of the manufacturing cost of solid capacitors in recent years. With the precipitation of technology at this time, the commercialization of solid capacitors is just around the corner.
Chip capacitors further developed
The biggest advantage of the chip capacitor compared to the traditional point solution capacitor is that it can be installed in the machine, which is more suitable for the automation and mass production of industrial development. In recent years, the patent protection period of chip capacitors is coming to an end, and the product specifications are rapidly expanding. The production technology of capacitors is constantly developing, and the manufacturing cost and material cost are also greatly reduced. The acceleration of the industrial automation process will also bring the first conditions for the development of chip capacitors.
