How to distinguish the size of multiplayer ceramic chip capacitors?

How to distinguish the size of the chip capacitor, the chip capacitor is very small, there is no printing above, this is related to its production process (the chip capacitor is sintered at high temperature, so no way to print on its surface), and patch The resistance is screen printing.

The patch naming scheme is also different from ordinary capacitors:

0805: refers to the size of the chip capacitor, which is expressed in inches. 08 indicates a length of 0.08 inches and 05 indicates a width of 0.05 inches;

CG: It is the material used to make such capacitors. This material is generally suitable for capacitors below 10000 PF.

102: refers to the capacity of the capacitor, the first two are significant figures, the latter 2 indicates how many zero 102 = 10 × 102, which is = 1000PF;

J: The accuracy of the capacitance value required to reach the capacitance is 5%, and the dielectric material and error accuracy are paired.

500: The required withstand voltage of the capacitor is 50V. The same number in front of the 500 is a valid number, followed by the number of zeros;

N: refers to the end material. Now the general term refers to three-layer electrodes (silver/copper layers), nickel, and tin;

T: refers to the packaging method. T stands for tape packaging, B stands for plastic box bulk packaging;

The color of the SMD capacitor, which is much more common than usual, is lighter yellow than the cardboard box, and grayish blue, which will produce different differences in the specific production process.
