                  由于采用了新型的固态电解质,固态电解电容具有液态电解电容无法企及的优良特性。这些电气性能对于提高计算机系统中以高频为特征的应用显得尤为重要。固态电解电容的多种优良特性可以为主板提供进补疗效,其优势主要有三点。

                  Due to the use of a new type of solid electrolyte, the solid-state electrolytic capacitor has excellent characteristics that cannot be achieved by liquid electrolytic capacitor. These electrical properties are very important to improve the application of high frequency in computer system. The advantages of solid-state electrolytic capacitor are mainly three points.

                  1.高稳定性

                  1. High stability

                  固体铝电解电容可以持续在高温环境中稳定工作,使用固态铝电解电容可以直接提升主板性能。同时,由于其宽温度范围的稳定阻抗,适于电源滤波。它可以有效地提供稳定充沛的电源,在超频中尤为重要。

                  Solid aluminum electrolytic capacitor can work stably in high temperature environment. The performance of main board can be improved directly by using solid aluminum electrolytic capacitor. At the same time, due to its stable impedance in a wide temperature range, it is suitable for power filter. It can effectively provide stable and abundant power supply, especially in overclocking.

                  固态电容在高温环境中仍然能正常工作,保持各种电气性能。其电容量在全温度范围变化不超过15%,明显优于液态电解电容。同时固态电解电容的电容量与其工作电压基本无关,从而保证其在电压波动环境中稳定工作。

                  Solid state capacitors can still work normally in high temperature environment and maintain various electrical properties. The variation of capacitance is 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 the solid-state electrolytic capacitor is basically independent of its working voltage, so as to ensure its stable operation in the voltage fluctuation environment.

                  2.寿命长

                  2. Long life

                  固态铝电解电容具有极长的使用寿命(使用寿命超过50 年)。与液态铝电解电容相比,可以算作“长命百岁”了。它不会被击穿,也不必担心液态电解质干涸以及外泄影响主板稳定性。由于没有液态电解质诸多问题的困扰,固态铝电解电容使主板更加稳定可靠。

                  Solid state aluminum electrolytic capacitors have very long service life (more than 50 years). Compared with liquid aluminum electrolytic capacitor, it can be regarded as "long life". It will not be broken down, and there is no need to worry about the liquid electrolyte drying up and leakage affecting the stability of the motherboard. Due to the lack of liquid electrolyte, solid aluminum electrolytic capacitor makes the motherboard more stable and reliable.

                  固态的电解质在高热环境下不会像液态电解质那样蒸发膨胀,甚至燃烧。即使电容的温度超过其耐受极限,固态电解质仅仅是熔化,这样不会引发电容金属外壳爆裂,因而十分安全。工作温度直接影响到电解电容的寿命,固态电解电容与液态电解电容在不同温度环境下寿命明显较长。

                  Solid electrolytes will not expand or even burn like liquid electrolytes in high heat environment. Even if the temperature of the capacitor exceeds its tolerance limit, the solid electrolyte will only melt, which will not cause the metal shell of the capacitor to burst, so it is very safe. The working temperature directly affects the life of electrolytic capacitor, and the life of solid electrolytic capacitor and liquid electrolytic capacitor is significantly longer in different temperature environment.

                  3.低ESR 和高额定纹波电流

                  3. Low ESR and high rated ripple current

                  ESR(Equivalent Series Resistance)指串联等效电阻,是电容非常重要的指标。ESR越低,电容充放电的速度越快,这个性能直接影响到微处理器供电电路的退藕性能,在高频电路中固态电解电容的低ESR 特性的优势更加明显。可以说,高频下低ESR 特性是固态电解电容与液态电容性能差别的分水岭。

                  ESR (equivalent series resistance) refers to series equivalent resistance, which is a very important index of capacitance. The lower the ESR is, the faster the charging and discharging speed of capacitor is. This performance directly affects the decoupling performance of microprocessor power supply circuit. In high frequency circuit, the advantage of low ESR characteristic of solid-state electrolytic capacitor is more obvious. It can be said that the low ESR characteristic at high frequency is the watershed of the performance difference between solid electrolytic capacitor and liquid electrolytic capacitor.

                  固态铝电解电容的ESR 非常低,同时具有非常小的能量耗散。在高温、高频和高功率工作条件下固态电容的极低ESR 特性可以充分吸收电路中电源线间产生的高幅值电压,防止其对系统的干扰。

                  The ESR of solid-state aluminum electrolytic capacitor is very low and has very small energy dissipation. Under high temperature, high frequency and high power operating conditions, the very low ESR characteristic of solid state capacitor can fully absorb the high amplitude voltage generated between power lines in the circuit to prevent its interference to the system.
