The biggest role of solid state capacitor lies in its stability and explosion-proof performance.
As the solid state capacitor uses conductive polymer products as dielectric materials, the material will not react with aluminum oxide and will not explode after being energized; At the same time, it is solid, so there is no explosion due to thermal expansion. Solid state capacitors have the advantages of environmental protection, low impedance, high and low temperature stability, high ripple resistance and high reliability. They are the most advanced electrolytic capacitor products. As the characteristics of solid state capacitance are much better than that of liquid aluminum capacitance, the solid state capacitance has a temperature resistance of 260 degrees, and has good conductivity, frequency characteristics and life. It is suitable for low voltage and high current applications, mainly used in digital products such as thin DVD, projectors and industrial computers. In recent years, it has also been widely used by computer board products.
Main application fields of solid aluminum capacitors:
1. The impedance frequency curve of solid aluminum capacitor is similar to that of ideal capacitor, so it is especially suitable for filtering capacitor to remove various noises such as ripple, pulse, digital, static electricity and audio in the circuit;
2. The solid aluminum capacitor has large ripple current, so it can be used as a filter capacitor of switching power supply, greatly reducing the number or volume of capacitors used, and making the circuit smaller;
3. Solid state aluminum capacitors can discharge rapidly and can be used as backup capacitors in high-speed circuits that consume large current;
4. The ESR value of solid aluminum capacitor hardly changes with temperature, so it can be applied to equipment in low temperature environment (as low as - 55 ℃);
5. The solid aluminum capacitor has an extremely long life (the life at 85 ℃ can reach 50000h, and the solid aluminum capacitor roughly follows the rule of 10 times of the service life/20 ℃ drop in temperature), so it can be used for industrial equipment that has been used for a long time.
