(1). 直流鋁電解電容應(yīng)按正確的極性使用 DC electrolytic capacitors are polarized 當(dāng)直流鋁電解電容器按反極性接入電路時(shí)，電容器會(huì)導(dǎo)致電子線路短路，由此產(chǎn)生的電流會(huì) 引致電容器損壞。若電路中有可能在負(fù)引線施加正極電壓，請(qǐng)選無(wú)極性產(chǎn)品。
When reverse voltage is applied on DC electrolytic capacitor, the capacitor will becomes short-circuited please use no polarized capacitors in the circuit be damage due to abnormal current flows through the capacitors since the circuit where the positive voltage may be applied to the cathode terminal.
(2). 在額定工作電壓以下作用 Use capacitor within rated voltage 當(dāng)電容器上所施加電壓高于額定工作電壓時(shí)，電容器的漏電流將上升，其電氣特性將在短時(shí)內(nèi)劣 化直至損壞。請(qǐng)注意電壓峰值勿超出額定工作電壓。
When capacitor is used at higher voltage than the rated voltage, leakage current increases, characteristics drastically deteriorate and damage in a short period may occur as a result. Please take extra caution that the peak voltage should not exceed the rated voltage.
(3). 作快速充放電使用 Charge and discharge application.
當(dāng)常規(guī)電容器被用作快速充電用途。其使用壽命可能會(huì)因?yàn)槿萘肯陆担瑴囟燃眲∩仙榷s減。
When aluminum electrolytic capacitors for general purpose are employed in rapid charge and discharge application, its life expectancy may be shortened by capacitance decrease, heat rise, etc.
(4). 電容器貯存 Store the capacitor. 當(dāng)鋁電解電容器作了長(zhǎng)期貯存后，其漏電流通常升高，貯存溫度愈高，漏電流上升愈快。因此應(yīng) 注意貯存環(huán)境的選擇，在電容器上施加電壓后，漏電流值將不斷下降，在鋁電解電容器的漏電流值上 升對(duì)電路有不良影響的，請(qǐng)?jiān)谑褂们俺潆娞幚怼?/p>
I creased leakage current is common in aluminum capacitors which have been stored for long period of tine. The Higher the storage temperature, the higher the leakage current decreases gradually as voltage is applied to the capacitor. In cases where increased leakage current causes problems in the circuit, apply voltage (aging) before using.
(5). 施加紋波電流應(yīng)少于額定值 Ripple current applied to capacitor should not exceed the rated value. 施加紋波電流超過(guò)額定值后，會(huì)導(dǎo)致電容器體過(guò)熱，容量下降，壽命縮短。所施加紋波電壓的峰 值應(yīng)少于額定工作電壓。 Excessive heat will reduce capacitance and result in shortened life of capacitor if ripple currents exceeding the specified rated value are applied. The peak value of the ripple voltage should be less than the rated voltage.
(6). 使用環(huán)境溫度 Ambient temperature. 鋁電解電容器的使用壽命會(huì)受到環(huán)境溫度的影響。據(jù)科學(xué)統(tǒng)計(jì)，使用環(huán)境溫度下降 10℃其使用壽 命增加 1 倍。
The ambient temperature affects life of the aluminum electrolytic capacitor. It is generally stated, that life doubles for each 10℃ decrease in temperature. 6
(7). 引出線強(qiáng)度 Lead stress 當(dāng)拉力施加到電容器引出線，該拉力將作用于電容器內(nèi)部，這將導(dǎo)致電容器內(nèi)部短路，開(kāi)路或漏 電流上升。在電容器焊裝到電路板，請(qǐng)勿強(qiáng)烈搖動(dòng)電容器。
When a strong force is applied to the lead wires or terminals, stress is put on the internal connections. This may result in short circuit, open circuit or increased leakage current. It is not advisable to bend or handle a capacitor after it has been soldered to the PC board.
(8). 焊接過(guò)程耐熱性 Heat resistance at the soldering process 鋁電解電容器裝至電路板進(jìn)行浸焊或波焊時(shí)，其塑料套管可能因焊接時(shí)間過(guò)長(zhǎng)、溫度過(guò)高而發(fā)生破 裂或二次收縮。
In the dip soldering process of PC board with aluminum electrolytic capacitors mounted, secondary shrinkage or crack of PVC sleeve may be observed when solder temperature is too high or dipping time is too long.
(9). 電路板的安裝孔孔距及安裝位置 Hole pitch and POSTTTION of PC board. 電路板安裝孔的設(shè)計(jì)應(yīng)與產(chǎn)品說(shuō)明書(shū)的引線腳距相一致，如果將電容器強(qiáng)行插入孔距不配套的電 路板，那么會(huì)有應(yīng)力作用于引出線，這將導(dǎo)致短路或漏電流上升。
A PC board must be designed so its hole pitch coincides with the lead pitch (lead spacing) of the capacitor specified by the catalog or specifications. When a capacitor is forcibly inserted into an unmatched hole pitch, a stress is put on the leads This could result in a short circuit or increased leakage current.
