三瑩貼片電容的額定電壓和耐壓值往往是由貼片電容制造工藝和自身的材料材質決定的；其中，絕緣電阻是耐壓值高低的關鍵所在。
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.
要想知道三瑩貼片電容的耐壓值和電壓，首先要明確下貼片電容的額定電壓和耐壓的概念。
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.
耐壓值：指的是電氣方面，能承受的最大電壓，即一個電氣或者電子元件能正常工作的最大承受電壓，超過這個值元件就不能正常工作，比如上面說的電容，一旦超過其耐壓值就會被擊穿，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.
額定電壓：指的是產品標準的工作電壓。在此電壓以下，該104電容可以持續正常工作。
Rated voltage: refers to the standard working voltage of the product. Below this voltage, the 104 capacitor can continue to work normally.
不論是貼片電容（MLCC）還是瓷片電容，因為市場需求不同，工廠都會生產不同的耐電壓產品，耐電壓和額定電壓有對應關系（不過各品牌的對應關系系數可能不同）。
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).
以韓國三瑩貼片電容為例：
Take the Korean Sanying chip capacitor as an example:
1、常規貼片電容的可選額定電壓包括4V、6.3、10V、16V 、25V、35V、50V，對應的耐電壓范圍是額定電壓的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、中壓貼片電容：額定電壓和耐電壓的對應關系：
Medium voltage chip capacitance: corresponding relationship between rated voltage and withstand voltage:
50V~1000V：耐壓≤額定電壓×1.5
50V~1000V: withstand voltage ≤ rated voltage × one point five
1KV以上：耐壓≤額定電壓×1.2
Above 1KV: withstand voltage ≤ rated voltage × one point two
根據韓國三瑩貼片電容測試條件，以上耐壓值的測試時間是5秒鐘。
According to the capacitance test conditions of the Korean Sanying chip, the test time for the above withstand voltage values is 5 seconds.
貼片電容普通系列耐壓：6.3V，10V，16V，25V，35V，50V。
Chip capacitor common series withstand voltage: 6.3V, 10V, 16V, 25V, 35V, 50V.
貼片電容高壓系列耐壓：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，貼片電容的耐壓及額定電壓和容量規格有很大的聯系，因為容值和耐壓往往是相互關聯的。常用容值規格下的額定電壓和耐壓。
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的精密容值規格，其額定電壓默認是50V
The default rated voltage of the precision capacitance specification of 1pF ～ 10nF is 50V
100nF容值規格的0603尺寸貼片電容常規額定電壓有50V和25V，而耐壓值最高只能做到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的容值規格常規的額定電壓是10V和25V，最高耐壓值只能做到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尺寸貼片電容，常規的額定電壓是10V，最大耐壓值只能做到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的容值規格常規額定電壓是6.3V和10V，最高耐壓只能做到16V
The normal rated voltage of 10uF is 6.3V and 10V, and the maximum withstand voltage is only 16V
22uF和47uF的大容值規格的0603尺寸貼片電容，其耐壓值只能達到6.3V，所以一般額定電壓也是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.
韓國三瑩貼片鋁電解電容具有高可靠性、優良的焊接性和和耐焊性，適用于回流爐和波峰焊。應用于隔直、耦合、旁路、鑒頻等電路中。
