1, the capacitance in the circuit generally use "C" plus number (such as capacitors C13 that number is 13). Capacitance is composed of two pieces of metal film against the intermediate element consisting of an insulating material and separated. The main characteristic of the capacitor is blocking the flow of communication. The size of the capacitance is capable of storing electrical energy represents the size of the capacitor impediment AC signal is called capacitance, frequency and capacity which AC signal related. Capacitive reactance XC = 1 / 2πf c (f represents the frequency of the AC signal, C represents capacitance) telephone species commonly used electrolytic capacitor capacitance ceramic capacitors, chip capacitors, monolithic capacitors, tantalum capacitors, and polyester capacitors ???
2. Recognition: Recognition capacitance and resistance identification method is basically the same, points straight standard method, color standard method and several standard method three kinds. The basic unit of capacitance with Farah (F), said other units are: millifarad (mF), microfarad (uF), mobility method (nF), picofarads (pF). Where: 1 farad = 103 = 106 microfarads millifarad = 109 nF = 1012 picofarads large-capacity capacitor whose capacitance value is directly marked on the capacitor as 10 uF / 16V small-capacity capacitor whose capacitance value of the capacitor with the letter representation or digital representation letter notation: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF digital notation: general capacity size with three digits, the first two represents a valid number, the third number is the magnification. Such as: 102 represents 10 × 102PF = 1000PF 224 represents 22 × 104PF = 0.22
3, the capacitance table symbol FGJKLM error tolerance ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%, such as: a ceramic capacitor 104J represents a capacity of 0. 1 uF, error of ± 5%.
