电解电容是一种应用极为广泛的电子元件，就我们日常生活中常用的液晶电视、笔记本电脑、ipad、数码相机、LDE节能灯等等都有电容的身影。今天红宝电子小编就给大家详细介绍下电解电容的命名规则以及电解电容常见的封装形式及意义。
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.
电解电容封装命名规则
Naming rules of electrolytic capacitor package
一般电解电容的耐压分档为6.3V，10V，16V，25V，50V等。
Generally, the withstand voltage grades of electrolytic capacitors are 6.3V, 10V, 16V, 25V, 50V, etc.
电解电容的常见封装形式
Common packaging forms of electrolytic capacitors
电解电容封装一般按尺寸大小可以分为：引线型（也叫直插型）、牛角型（也叫焊针型），螺栓型这三种。
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.
焊针型最常见的是二角焊针，但也有三角焊针、四角焊针和不规格的多角焊针型等。
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.
另外还有一种叫焊片型，不太常用，尺寸类似牛角型大小。
In addition, there is a type called solder, which is not commonly used, and its size is similar to that of ox horn.

电解电容封装的意义
Significance of electrolytic capacitor packaging
1.电解电容器通常是由金属箔(铝/钽)作为正电极,金属箔的绝薄膜或电解质聚合物构成；
1. The electrolytic capacitor is usually made of metal foil (aluminum / tantalum) as positive electrode, thin film of metal foil or electrolyte polymer;
2.钽电解电容器的负电极通常采用二氧化锰。由于均以电解质作为负电极（注意和电介质区分），电解电容器因而得名。
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.有极性电解电容器通常在电源电路或中频、低频电路中起电源滤波、退耦、信号耦合及时间常数设定、隔直流等作用。一般不能用于交流电源电路，在直流电源电路中作滤波电容使用时，其阳极（正极）应与电源电压的正极端相连接，阴极（负极）与电源电压的负极端相连接，不能接反，否则会损坏电容器。
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.电解电容器广泛应用于家用电器和各种电子产品中，其容量范围较大，一般为1~1000μF，额定工作电压范围为6.3~450V。其缺点是介质损耗、容量误差较大（最大允许偏差为+100%、-20%），耐高温性较差，存放时间长容易失效。
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.
电解电容器广泛应用于家用电器和各种电子产品中，其容量范围较大，一般为1~33000μF，额定工作电压范围为6.3~700V。其缺点是介质损耗、容量误差较大（最大允许偏差为+100%、-20%），耐高温性较差，存放时间长容易失效。
