The rated voltage and withstand voltage of Sanying chip capacitor are often determined by the manufacturing process of the chip capacitor and its own material; Among them, insulation resistance is the key to withstand voltage.

　　要想知道三莹贴片电容的耐压值和电压，首先要明确下贴片电容的额定电压和耐压的概念。

　　In order to know the withstand voltage value and voltage of the chip capacitor, the concept of the rated voltage and withstand voltage of the lower chip capacitor should be clarified first.

　　耐压值：指的是电气方面，能承受的最大电压，即一个电气或者电子元件能正常工作的最大承受电压，超过这个值元件就不能正常工作，比如上面说的电容，一旦超过其耐压值就会被击穿，不能正常工作。

　　Withstand voltage value: refers to the maximum voltage that an electrical or electronic component can withstand electrically, that is, the maximum withstand voltage that an electrical or electronic component can work normally. If it exceeds this value, the component cannot work normally. For example, the capacitance mentioned above will be broken down once it exceeds its withstand voltage value, and cannot work normally.

　　额定电压：指的是产品标准的工作电压。在此电压以下，该104电容可以持续正常工作。

　　Rated voltage: refers to the standard working voltage of the product. Below this voltage, the 104 capacitor can continue to work normally.

　　不论是贴片电容（MLCC）还是瓷片电容，因为市场需求不同，工厂都会生产不同的耐电压产品，耐电压和额定电压有对应关系（不过各品牌的对应关系系数可能不同）。

　　Because of different market demands, the factory will produce different withstand voltage products, whether it is chip capacitors (MLCC) or ceramic capacitors. The withstand voltage and rated voltage have a corresponding relationship (however, the corresponding relationship coefficient of each brand may be different).

　　以韩国三莹贴片电容为例：

　　Take the Korean Sanying chip capacitor as an example:

　　1、常规贴片电容的可选额定电压包括4V、6.3、10V、16V 、25V、35V、50V，对应的耐电压范围是额定电压的3倍即12V~150V。

　　The optional rated voltages of conventional chip capacitors include 4V, 6.3, 10V, 16V, 25V, 35V and 50V, and the corresponding withstand voltage range is 3 times of the rated voltage, i.e. 12V~150V.

　　2、中压贴片电容：额定电压和耐电压的对应关系：

　　Medium voltage chip capacitance: corresponding relationship between rated voltage and withstand voltage:

　　50V~1000V：耐压≤额定电压×1.5

　　50V~1000V: withstand voltage ≤ rated voltage × one point five

　　1KV以上：耐压≤额定电压×1.2

　　Above 1KV: withstand voltage ≤ rated voltage × one point two

　　根据韩国三莹贴片电容测试条件，以上耐压值的测试时间是5秒钟。

　　According to the capacitance test conditions of the Korean Sanying chip, the test time for the above withstand voltage values is 5 seconds.

　　贴片电容普通系列耐压：6.3V，10V，16V，25V，35V，50V。

　　Chip capacitor common series withstand voltage: 6.3V, 10V, 16V, 25V, 35V, 50V.

　　贴片电容高压系列耐压：100V，160V，200V，250V，400V，500V，630V，1KV，2KV。

　　High voltage series withstand voltage of chip capacitor: 100V, 160V, 200V, 250V, 400V, 500V, 630V, 1KV, 2KV.

　　另外，贴片电容的耐压及额定电压和容量规格有很大的联系，因为容值和耐压往往是相互关联的。常用容值规格下的额定电压和耐压。

　　In addition, the withstand voltage and rated voltage of the chip capacitor are closely related to the capacity specification, because the capacitance and withstand voltage are often interrelated. Rated voltage and withstand voltage under common capacity specifications.

　　1pF～10nF的精密容值规格，其额定电压默认是50V

　　The default rated voltage of the precision capacitance specification of 1pF ～ 10nF is 50V

　　100nF容值规格的0603尺寸贴片电容常规额定电压有50V和25V，而耐压值最高只能做到100V

　　The nominal rated voltage of 0603 chip capacitor with 100nF capacitance specification is 50V and 25V, while the maximum withstand voltage can only be 100V

　　1uF的容值规格常规的额定电压是10V和25V，最高耐压值只能做到50V

　　The normal rated voltage of 1uF is 10V and 25V, and the maximum withstand voltage can only be 50V

　　2.2uF和4.7uF的0603尺寸贴片电容，常规的额定电压是10V，最大耐压值只能做到25V

　　For 0603 chip capacitors of 2.2uF and 4.7uF, the normal rated voltage is 10V, and the maximum withstand voltage can only be 25V

　　10uF的容值规格常规额定电压是6.3V和10V，最高耐压只能做到16V

　　The normal rated voltage of 10uF is 6.3V and 10V, and the maximum withstand voltage is only 16V

　　22uF和47uF的大容值规格的0603尺寸贴片电容，其耐压值只能达到6.3V，所以一般额定电压也是6.3V。

　　The withstand voltage of 0603 chip capacitors with large capacitance specifications of 22uF and 47uF can only reach 6.3V, so the general rated voltage is 6.3V.

　　韩国三莹贴片铝电解电容具有高可靠性、优良的焊接性和和耐焊性，适用于回流炉和波峰焊。应用于隔直、耦合、旁路、鉴频等电路中。

　　The Korean Sanying chip aluminum electrolytic capacitor has high reliability, excellent weldability and solderability, and is suitable for reflow furnace and wave soldering. It is used in such circuits as isolation, coupling, bypass and frequency discrimination.
