SMD capacitors (monolithic ceramic capacitors) is currently a large amount of commonly used components, the capacitor in terms of different specifications, different specifications have different uses. SMD capacitance size representation in two ways, one is expressed in inches, one is expressed in millimeters.
SMD capacitor naming:
The naming of a SMD capacitor includes the dimensions of the SMD capacitor, the material used for the SMD capacitor, the required accuracy, the required voltage, the required capacity, the requirements of the terminal, and the packaging requirements. Generally, ordering SMD capacitors need to provide the parameters and the required brand. For example Fenghua series of SMD capacitors named: 0805CG102J500NT
0805: refers to the size of the SMD capacitor is expressed in inches. 08 means the length is 0.08 inches and 05 means the width is 0.05 inches;
CG: refers to the material used to make this capacitor, the material is generally suitable for less than 10000PF capacitance, 102: refers to the capacitance, the first two digits are significant digits, followed by 2 indicates how many zero 102 = 10 × 102 that is 1000PF;
J: is the capacity of the capacitor to achieve the required error accuracy of 5%, the accuracy of the media material and the error is paired;
500: It is required to withstand the capacitor withstand voltage of 50V;
N: refers to the end of the material, the ends are now generally refers to the three electrodes (silver / copper layer), nickel, tin;
T: refers to the packaging, said taping packaging;
B: refers to the plastic box, bulk packaging.
The color of SMD capacitor:
Conventional colors are: a little lighter yellow than cartons, and grayish green, which can give rise to different differences in a particular production process.
There is no printed character above the capacitance, which is related to his production process (SMD capacitors are sintered surface at high temperature, so there is no way to print on the surface), and SMD resistors are made of silk screen (you can print mark). smd capacitors have high-voltage SMD capacitors in the ordinary chip capacitors.
Series voltage is 6.3V, 10V, 16V, 25V, 50V, 100V, 200V, 500V, 1000V, 2000V, 3000V, 4000V.
SMD capacitance size representation in two ways, one is expressed in inches, one is expressed in millimeters, SMD capacitor series models are 0201,0402,0603,0805,1206,1210,1812 , 2010,2225 and so on.
