First of all, we need to understand the voltage value of high voltage ceramic chip capacitance and the identification method of capacitance.
The usual method is the direct notation, that is, if the number is 0.001, then it stands for 0.001uF-1 nF. if it is 10n, then it is 10nFand the same 100p is 100pF. Of course, there is also a direct representation of unmarked units, using a 1 / 4 digit representation, a capacity unit of PF, such as 350 for 350 and 350pFF3 for 3pF0. 5 for 0.5pF.
Then there is the color code representation. Along the direction of the capacitor lead, different numbers are represented by different colors. The third color represents the number of zeros (in units of PF) after the effective number. The meaning of the color is: black, brown, red, yellow, green, blue, blue, purple, gray, and white.
Porcelain chip capacitor has high voltage porcelain piece and ordinary porcelain chip capacitor, ordinary porcelain piece capacitor withstand voltage is 50 V in the past, high voltage porcelain piece capacitor has several hundred volts, have several kilowatts, mark XXKV below capacity value commonly. 1J stands for 6.3 × 10 ~ (3) V ~ (63) V ~ (2) F = 3.15 × 100 ~ (31) V ~ (3) A represents 1.0 × 1000 ~ (10) V ~ (-1) K = 8.0 × 10 ~ (-1) V. The number is 4, such as 4Z for 90000V.
There are also two common ways to mark the voltage resistance of capacitors. One is to print the voltage value directly on the capacitor, and the other is to combine a number and a letter.
In fact, as long as you can accurately grasp the relevant logo, you can easily determine the value of the voltage resistance according to its logo. Different representations represent different meanings.
How to detect the voltage value of high voltage ceramic chip capacitance? Measuring instruments and voltages are used to detect the voltage resistance of high-voltage ceramic chip capacitors. The detected voltage is twice as high as the rated voltage.
The above knowledge about the voltage value of high voltage ceramic chip capacitance comes from the R & D department of Dongguan Zhixu Electronics Co., Ltd. More information can be found on the website.

High voltage chip capacitor.
There are also two common methods for marking the voltage resistance of capacitors. One is to print the voltage value directly on the capacitor; the other is to combine a number and a letter. The voltage value of the capacitance of a high-voltage ceramic chip is measured by measuring instruments and voltage-resistant machines. The detected voltage is twice as high as the rated voltage.
