1. High stability
Solid aluminum electrolytic capacitors can continue to work stably in high temperature environment, using solid aluminum electrolytic capacitors can directly improve the performance of the motherboard. At the same time, it is suitable for power filter because of its stable impedance over a wide temperature range. It can effectively provide a stable and abundant power supply, especially in overclocking.
Solid state capacitors can still work normally in high temperature environment and maintain various electrical properties. Its capacitance varies less than 15% in the whole temperature range, which is obviously better than that of liquid electrolytic capacitor. At the same time, the capacitance of solid-state electrolytic capacitor is basically independent of its working voltage, so as to ensure its stable operation in the voltage fluctuation environment.
2. Long life span
Solid aluminum electrolytic capacitors have extremely long service life (service life of more than 50 years). Compared with liquid aluminum electrolytic capacitor, can be counted as "longevity". It will not be broken down, and do not have to worry about liquid electrolyte drying and leakage affecting the stability of the motherboard. Because there is no liquid electrolyte problems, solid aluminum electrolytic capacitor makes the motherboard more stable and reliable.
Solid electrolytes do not evaporate and expand, or even burn, as liquid electrolytes do under high heat. Even if the temperature of the capacitor exceeds its tolerance limit, the solid electrolyte simply melts, which does not cause the capacitor's metal casing to burst, so it is safe.
The working temperature directly affects the life of electrolytic capacitors. The life of solid electrolytic capacitors and liquid electrolytic capacitors is obviously longer in different temperature environments.
3. Low ESR and high ripple current rating
The ESR (EquivalentSeriesResistance) refers to the equivalent series resistance, capacitance is very important. The lower the ESR is, the faster the capacitor is charged and discharged. This performance directly affects the de-coupling performance of the microprocessor power supply circuit. In the high-frequency circuit, the advantage of the solid-state electrolytic capacitor's low ESR characteristic is more obvious. It can be said that the high frequency and low ESR characteristics are the watershed between solid electrolytic capacitors and liquid capacitors. Solid-state aluminum electrolytic capacitors have very low ESR and very little energy dissipation. Under high temperature, high frequency and high power conditions, the very low ESR characteristics of solid-state capacitor can fully absorb the high amplitude voltage generated between the power lines in the circuit and prevent its interference to the system.
At present, the power consumption of the CPU is very large, the main frequency has far exceeded 1GHz, and the peak current of the CPU has reached 80A or more, and the output filter capacitor has been close to the critical point. Cpus, on the other hand, work in a variety of modes and spend most of their time switching between working modes. When the CPU changes from low power to full load, a large amount of energy required for the instantaneous (generally less than 5 milliseconds) CPU switching comes from the capacitor in the CPU power supply circuit. In this case, the high-speed charge-discharge feature of the solid-state capacitor can output the peak current at an instant to ensure adequate power supply and stable CPU operation.
