The unit of capacitance for chip capacitors is "Farad", represented by the letter "F". There is also a conversion unit smaller than F, which is MF (Mega Method) μ F. (Micro method), NF (Nano method), PF (Micro method). Due to the very large capacity of the capacitor "F" unit, what we usually see is μ F. The units of nF and pF. In common circuit diagrams μ F. Some PF omit the display of F μ、 The actual capacitance labeling method for P is generally less than 9900P, and P is used to represent greater than 0.01 μ (including 0.01) for μ Represent.

Chip capacitor capacity conversion: N (millimicron method) represents 1n=1000P; 10n=0.01 μ； 100n=0.1 μ。 Example: 3n3 represents 3300Pf 22N represents 0.022 μ F 470n represents 0.47 μ F

Direct labeling method for patch capacitors: 0.01 μ zero point zero four seven μ 3300pf and 560pf display the actual capacity without conversion.
Chip capacitors are expressed as power: 10 10 none=10P; 101 10 0=100P; 102 10 00=1000P; 103 10 000=0.01; 104 10 0000=0.1; 105 10 00000=1 μ。 The first two digits are capacity. The third digit is the power, and the unit of the power is P. For example, 221 means 22 plus one zero equals 220P, 472 means 47 plus two zeros equals 4700P, 683 means 68 plus three zeros equals 0.068 μ F

SMD capacitance is represented by a symbol: this symbol is mostly used for SMD or small Electrolytic capacitor, and its reading is somewhat similar to that expressed by power, so attention should be paid when using it. Its capacity unit is generally μ F level.

Chip capacitors can be identified based on these markings to determine their capacity and select the appropriate capacity to meet actual performance requirements. Simple annotation methods can easily grasp and understand relevant information.
