Due to the long-term use of the computer motherboard, overheating causes the capacitor electrolyte to heat and expand, the capacitance loses its function, and even exceeds the boiling point, causing the capacitor to expand and burst. So is it better to choose solid capacitor or liquid capacitor for computer motherboards?

When the computer motherboard is not energized for a long time, the electrolyte is likely to form a chemical reaction with alumina, causing an explosion when it is turned on or energized. If solid capacitors are used, such hidden dangers and dangers can be prevented.

The solid capacitor uses a conductive polymer product as the dielectric material. This material will not interact with alumina and will not explode after being energized. At the same time, it is a solid product, so naturally there is no explosion caused by thermal expansion. Up. Solid capacitors have excellent characteristics such as environmental protection, low impedance, high and low temperature stability, high ripple resistance and high reliability, and are the highest-end products among current electrolytic capacitor products. Since the characteristics of solid capacitors are far better than those of liquid aluminum capacitors, solid capacitors can withstand temperatures up to 260 degrees Celsius, and have good conductivity, frequency characteristics and life. They are suitable for low voltage and high current applications, and are mainly used in digital products such as thin DVD, Projector and industrial computer, etc.

Solid capacitors have a longer service life. At 105 degrees Celsius, the life of it and electrolytic capacitors is the same 2000 hours. After the temperature decreases, their life will increase, but the life of solid capacitors will increase even more. Generally, the operating temperature of capacitors is 70 degrees or more. Low. At this time, the life of solid capacitors may reach 23 years, which is almost 6 times that of electrolytic capacitors! We can understand that solid capacitors are of high quality. Generally speaking, more high-end computer motherboards use solid capacitors.
