Ceramic Capacitance Reading Method (1)

The capacity identification method of the ceramic capacitor (the method of calculating the capacitance according to the identification) is as follows: the identification method of the ceramic capacitor is basically the same as the identification method of the resistance, and is divided into three types: a straight label method, a color scale method and a digital standard method. The basic unit usage of the capacitor is (F), and other units are: millifarad (mF), microfarad (μF)/mju:/, nanofarad (nF), and picofarad (pF). Where: 1 Farad = 1000 millifarads (mF), 1 millifarad = 1000 microfarads (μF), 1 microfarad = 1000 nanofarads (nF), 1 nanofarad = 1000 picofarads (pF)

The capacitance of the ceramic capacitor is generally in pF (10 -12 power F). The early products are mostly labeled directly, such as 1000p, 220p, etc.; now generally expressed in common index, such as 102, 221, the first two The number is a valid number of the capacitance, and the last digit is the number of zeros added later. For example, 102 indicates that the effective number is 10, 2 indicates that 2 zeros are added later, that is, 1000pF; 221 indicates the effective number 22, and 1 indicates that it is later. Add 1 0, which is 220pF.
