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

主要由电路的短路导致，当短路电路中的电流超过1A，电容内部温度将会上升，内部压力增大封口橡胶将会凸起甚至开启，电容会因此释放出有害气体，此时需立刻断开电路并离开这个场合另外还有超电压使用、超高温使用、超额定纹波电流使用，都会导致产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）寿命失效 Life failure：

经过长时间使用后，固态铝电容的特性会发生衰减，例如容量下降、ESR上升等当使用时间超过额定寿命，电容的特性将劣化，可能导致电解质绝缘形成开路。

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。

6、电容寿命估算 Capacitor life estimation：

T0 - TX

L=L0×10 20

（1）L：某温度下的预期寿命（h)

L：At a certain temperature life expectancy(h)

（2）L0：额定寿命（h)

L0：rated life(h)

（3）T0：最高额定温度 (℃)

T0：The maximum rated temperature (℃)

（4）TX：实际环境温度 (℃)

TX：The actual environment temperature ( ℃)

7、固态铝电容的优越性 The superiority of the conductive polymer aluminum solid capacitor：

（1）低等效串联电阻 = 降低温度，稳定

Low equivalent series resistance = lower temperature, stability

（2）耐高纹波电流 = CPU，Memory，PCI Express电源模组设计的最佳选择

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

（3）高低温度变化下依然稳定

二、特别提醒 Special remind：1、漏电流 Leakage current：
（1）焊接热、运输途中的机械应力，都可能导致电容的漏电流增大

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

（2）但是，给产品施加不超过额定工作电压的直流电压时，漏电流会逐渐降低

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

（3）在不超过额定工作电压、额定上限温度的前提下，施加电压越高、环境温度越高，漏电流下降速度越快

current will decrease, On the premise of not more than the rated voltage, rated maximum temperature, with the increase of applied voltage, the higher the ambient temperature, the leakage current decreases faster.

2、固态铝电容的绝缘性 Insulation of conductive polymer aluminum solid capacitors：

（1）固态铝电容外的绝缘镀膜并不是绝对绝缘的,另外铝壳与负极引出线之间不绝缘

conductive polymer aluminum solid capacitors insulating coating is not insulated completely, the aluminum shell and the negative lead wire not insulated .

（2）安装的时候，请务必将铝壳、正负导针及PC板印刷图完全隔离开

When installing, please be sure to aluminum shell, positive and negative lead wire, PCB board completely separate.

3、工作环境的限制 Working conditions limit：

4、PCB板设计 PCB board design：

（1）不要将固态铝电容安装于热源组件周围或其上面

Don't be conductive polymer aluminum solid capacitors mounted on a heat source component around or above it.

（2）PCB板上的安装孔位，直径和间距要与电容导针的直径和针距相匹配

The PCB board installation hole, diameter and spacing to diameter and capacitance guide needle and needle distance matching.

5、并联电路 Parallel circuit：

当固态铝电容与另一液态铝电容并联时，由于固态电容具有低得多的ESR值因此，可能会有很大的纹波电流施加在固态电容上，这种情况下请谨慎选择电容规格。

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.
