Solid capacitors are called: solid aluminum electrolytic capacitors. The biggest difference between it and ordinary capacitors (ie, liquid aluminum electrolytic capacitors) is that different dielectric materials are used. The liquid aluminum capacitor dielectric material is the electrolyte, and the solid capacitor dielectric material is the conductive polymer.
Since the solid capacitor uses a conductive polymer product as a dielectric material, the material does not act on the alumina, and does not explode after being energized; at the same time, it is a solid product, and naturally there is no burst due to thermal expansion. The situation is gone. Solid capacitors are environmentally friendly, low impedance, high and low temperature stability, high ripple resistance and high reliability. They are the highest-end products in electrolytic capacitors.
A little bit of solid capacitor:
Solid aluminum electrolytic capacitors can continue to work stably in high temperature environments. Solid aluminum electrolytic capacitors can directly improve the performance of the motherboard. At the same time, it is suitable for power supply filtering due to its stable impedance over a wide temperature range. It can effectively provide a stable and abundant power supply, which is especially important in overclocking.
Solid capacitors still work well in high temperature environments, maintaining a variety of electrical performance. Its capacitance does not vary by more than 15% over the full temperature range, significantly better than liquid electrolytic capacitors. At the same time, the capacitance of the solid electrolytic capacitor is basically independent of its working voltage, thus ensuring its stable operation in a voltage fluctuation environment.
2. Long life
Solid aluminum electrolytic capacitors have an extremely long service life (more than 50 years of service life). It will not be broken down, and there is no need to worry about the electrolyte electrolyte drying and leakage affecting the stability of the motherboard. Due to the lack of liquid electrolyte problems, solid aluminum electrolytic capacitors make the motherboard more stable and reliable.
Solid electrolytes do not evaporate and even burn like liquid electrolytes in high heat environments. Even if the temperature of the capacitor exceeds its tolerance, the solid electrolyte is only melted, which does not cause the capacitor metal casing to burst and is therefore safe.
3. Low ESR and high rated ripple current
ESR (Equivalent Series Resistance) refers to the series equivalent resistance, which is a very important indicator of capacitance. The lower the ESR, the faster the capacitor charge and discharge. This performance directly affects the decoupling performance of the microprocessor power supply circuit. The advantages of the low ESR characteristics of the solid electrolytic capacitor in the high frequency circuit are more obvious. Solid aluminum electrolytic capacitors have very low ESR and very low energy dissipation. The extremely low ESR characteristics of solid capacitors under high temperature, high frequency and high power operating conditions can fully absorb the high amplitude voltage generated between the power lines in the circuit to prevent its interference with the system.
