由于采用了新型的固態(tài)電解質(zhì)，固態(tài)電解電容具有液態(tài)電解電容無(wú)法企及的優(yōu)良特性。這些電氣性能對(duì)于提高計(jì)算機(jī)系統(tǒng)中以高頻為特征的應(yīng)用顯得尤為重要。固態(tài)電解電容的多種優(yōu)良特性可以為主板提供進(jìn)補(bǔ)療效，其優(yōu)勢(shì)主要有三點(diǎn)。
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.高穩(wěn)定性
1. High stability
固體鋁電解電容可以持續(xù)在高溫環(huán)境中穩(wěn)定工作，使用固態(tài)鋁電解電容可以直接提升主板性能。同時(shí)，由于其寬溫度范圍的穩(wěn)定阻抗，適于電源濾波。它可以有效地提供穩(wěn)定充沛的電源，在超頻中尤為重要。
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.
固態(tài)電容在高溫環(huán)境中仍然能正常工作，保持各種電氣性能。其電容量在全溫度范圍變化不超過(guò)15％，明顯優(yōu)于液態(tài)電解電容。同時(shí)固態(tài)電解電容的電容量與其工作電壓基本無(wú)關(guān)，從而保證其在電壓波動(dòng)環(huán)境中穩(wěn)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.壽命長(zhǎng)
2. Long life
固態(tài)鋁電解電容具有極長(zhǎng)的使用壽命(使用壽命超過(guò)50 年)。與液態(tài)鋁電解電容相比，可以算作“長(zhǎng)命百歲”了。它不會(huì)被擊穿，也不必?fù)?dān)心液態(tài)電解質(zhì)干涸以及外泄影響主板穩(wěn)定性。由于沒(méi)有液態(tài)電解質(zhì)諸多問(wèn)題的困擾，固態(tài)鋁電解電容使主板更加穩(wěn)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.
固態(tài)的電解質(zhì)在高熱環(huán)境下不會(huì)像液態(tài)電解質(zhì)那樣蒸發(fā)膨脹，甚至燃燒。即使電容的溫度超過(guò)其耐受極限，固態(tài)電解質(zhì)僅僅是熔化，這樣不會(huì)引發(fā)電容金屬外殼爆裂，因而十分安全。工作溫度直接影響到電解電容的壽命，固態(tài)電解電容與液態(tài)電解電容在不同溫度環(huán)境下壽命明顯較長(zhǎng)。
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 和高額定紋波電流
3. Low ESR and high rated ripple current
ESR(Equivalent Series Resistance)指串聯(lián)等效電阻，是電容非常重要的指標(biāo)。ESR越低，電容充放電的速度越快，這個(gè)性能直接影響到微處理器供電電路的退藕性能，在高頻電路中固態(tài)電解電容的低ESR 特性的優(yōu)勢(shì)更加明顯。可以說(shuō)，高頻下低ESR 特性是固態(tài)電解電容與液態(tài)電容性能差別的分水嶺。
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.
固態(tài)鋁電解電容的ESR 非常低，同時(shí)具有非常小的能量耗散。在高溫、高頻和高功率工作條件下固態(tài)電容的極低ESR 特性可以充分吸收電路中電源線間產(chǎn)生的高幅值電壓，防止其對(duì)系統(tǒng)的干擾。
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.
