電解電容是一種應(yīng)用極為廣泛的電子元件，就我們?nèi)粘Ｉ钪谐Ｓ玫囊壕щ娨暋⒐P記本電腦、ipad、數(shù)碼相機(jī)、LDE節(jié)能燈等等都有電容的身影。今天紅寶電子小編就給大家詳細(xì)介紹下電解電容的命名規(guī)則以及電解電容常見的封裝形式及意義。
Electrolytic capacitor is a kind of widely used electronic components, such as LCD TV, notebook computer, iPad, digital camera, LDP energy-saving lamp and so on. Today, Hongbao electronic editor will give you a detailed introduction to the naming rules of electrolytic capacitors and the common packaging forms and significance of electrolytic capacitors.
電解電容封裝命名規(guī)則
Naming rules of electrolytic capacitor package
一般電解電容的耐壓分檔為6.3V，10V，16V，25V，50V等。
Generally, the withstand voltage grades of electrolytic capacitors are 6.3V, 10V, 16V, 25V, 50V, etc.
電解電容的常見封裝形式
Common packaging forms of electrolytic capacitors
電解電容封裝一般按尺寸大小可以分為：引線型（也叫直插型）、牛角型（也叫焊針型），螺栓型這三種。
Electrolytic capacitor package can be generally divided into lead type (also known as plug-in type), ox horn type (also known as solder pin type) and bolt type.
焊針型最常見的是二角焊針，但也有三角焊針、四角焊針和不規(guī)格的多角焊針型等。
The most common type of welding pin is the two corner welding pin, but there are also triangle welding pin, four corner welding pin and non-standard multi angle welding pin.
另外還有一種叫焊片型，不太常用，尺寸類似牛角型大小。
In addition, there is a type called solder, which is not commonly used, and its size is similar to that of ox horn.

電解電容封裝的意義
Significance of electrolytic capacitor packaging
1.電解電容器通常是由金屬箔(鋁/鉭)作為正電極,金屬箔的絕薄膜或電解質(zhì)聚合物構(gòu)成；
1. The electrolytic capacitor is usually made of metal foil (aluminum / tantalum) as positive electrode, thin film of metal foil or electrolyte polymer;
2.鉭電解電容器的負(fù)電極通常采用二氧化錳。由于均以電解質(zhì)作為負(fù)電極（注意和電介質(zhì)區(qū)分），電解電容器因而得名。?
2. The negative electrode of tantalum electrolytic capacitor is usually manganese dioxide. Because of the electrolyte as the negative electrode (pay attention to distinguish from the dielectric), the electrolytic capacitor gets its name. A kind of
3.有極性電解電容器通常在電源電路或中頻、低頻電路中起電源濾波、退耦、信號耦合及時(shí)間常數(shù)設(shè)定、隔直流等作用。一般不能用于交流電源電路，在直流電源電路中作濾波電容使用時(shí)，其陽極（正極）應(yīng)與電源電壓的正極端相連接，陰極（負(fù)極）與電源電壓的負(fù)極端相連接，不能接反，否則會(huì)損壞電容器。
3. The polar electrolytic capacitor usually plays the role of power filter, decoupling, signal coupling, time constant setting, DC isolation and so on in power supply circuit or intermediate frequency and low frequency circuit. Generally, it can not be used in AC power supply circuit. When it is used as filter capacitor in DC power supply circuit, its anode (positive pole) should be connected with the positive terminal of power supply voltage, and the cathode (negative pole) should be connected with the negative terminal of power supply voltage. Otherwise, the capacitor will be damaged.
4.電解電容器廣泛應(yīng)用于家用電器和各種電子產(chǎn)品中，其容量范圍較大，一般為1~1000μF，額定工作電壓范圍為6.3~450V。其缺點(diǎn)是介質(zhì)損耗、容量誤差較大（最大允許偏差為+100%、-20%），耐高溫性較差，存放時(shí)間長容易失效。
4. Electrolytic capacitor is widely used in household appliances and various electronic products, its capacity range is large, generally 1 ~ 1000 μ F, and the rated working voltage range is 6.3 ~ 450 v. Its disadvantages are large medium loss and capacity error (the maximum allowable deviation is + 100%, - 20%), poor high temperature resistance, long storage time and easy failure.
電解電容器廣泛應(yīng)用于家用電器和各種電子產(chǎn)品中，其容量范圍較大，一般為1~33000μF，額定工作電壓范圍為6.3~700V。其缺點(diǎn)是介質(zhì)損耗、容量誤差較大（最大允許偏差為+100%、-20%），耐高溫性較差，存放時(shí)間長容易失效。
