5、常見的失效模式 The common failure mode ：（1）偶然失效 Random failure：

主要由電路的短路導(dǎo)致，當(dāng)短路電路中的電流超過1A，電容內(nèi)部溫度將會(huì)上升，內(nèi)部壓力增大封口橡膠將會(huì)凸起甚至開啟，電容會(huì)因此釋放出有害氣體，此時(shí)需立刻斷開電路并離開這個(gè)場合另外還有超電壓使用、超高溫使用、超額定紋波電流使用，都會(huì)導(dǎo)致產(chǎn)品提前失效甚至短路。

Mainly caused by the short circuit, when the current short circuit in more than 1A, the internal temperature will increase the internal pressure increases, the capacitance, sealing rubber will be raised even opened, capacitor will release harmful gases, at this time should immediately disconnect the circuit and leave this place. In addition, the use of high voltage using high temperature,high rated ripple current use, will lead to product failure ahead even short circuit。

（2）壽命失效 Life failure：

經(jīng)過長時(shí)間使用后，固態(tài)鋁電容的特性會(huì)發(fā)生衰減，例如容量下降、ESR上升等當(dāng)使用時(shí)間超過額定壽命，電容的特性將劣化，可能導(dǎo)致電解質(zhì)絕緣形成開路。

After a long time after use, characteristics of capacitor will decay, such as capacity decreased, ESR increased, when the time exceeds the rated life, capacitance will deteriorate, may lead to electrolyte insulation open。

L0：rated life(h)

（3）T0：最高額定溫度 (℃)

T0：The maximum rated temperature (℃)

（4）TX：實(shí)際環(huán)境溫度 (℃)

7、固態(tài)鋁電容的優(yōu)越性 The superiority of the conductive polymer aluminum solid capacitor：

（1）低等效串聯(lián)電阻 = 降低溫度，穩(wěn)定

Low equivalent series resistance = lower temperature, stability

（2）耐高紋波電流 = CPU，Memory，PCI Express電源模組設(shè)計(jì)的最佳選擇

High ripple current = CPU, Memory, PCI best choice Express power module design

（3）高低溫度變化下依然穩(wěn)定

二、特別提醒 Special remind：1、漏電流 Leakage current：
（1）焊接熱、運(yùn)輸途中的機(jī)械應(yīng)力，都可能導(dǎo)致電容的漏電流增大

Mechanical welding heat, transport stress, may cause the leakage current of the capacitor.

（2）但是，給產(chǎn)品施加不超過額定工作電壓的直流電壓時(shí)，漏電流會(huì)逐漸降低

However, applying a DC voltage does not exceed the rated working voltage to the product, the leakage.

（3）在不超過額定工作電壓、額定上限溫度的前提下，施加電壓越高、環(huán)境溫度越高，漏電流下降速度越快

5、并聯(lián)電路 Parallel circuit：

當(dāng)固態(tài)鋁電容與另一液態(tài)鋁電容并聯(lián)時(shí)，由于固態(tài)電容具有低得多的ESR值因此，可能會(huì)有很大的紋波電流施加在固態(tài)電容上，這種情況下請(qǐng)謹(jǐn)慎選擇電容規(guī)格。

When the conductive polymer aluminum solid capacitor in parallel with another liquid aluminum capacitors, because the solid capacitor has a much lower ESR value, therefore, may have a ripple current great applied in solid capacitors, this case please choose carefully capacitor specifications.
