Capacitance recognition

1,the capacitance in circuit "C" and is commonly used in digital representation (such as a capacitor C13 said Numbers for 13). Capacitor is made up of two pieces of metal film,close to the middle separated by electric motors 12 volt insulating material and components. The characteristics of capacitance communication mainly blocking circulation. The size of the capacitance is said to store electrical energy,the size of the capacitance effect is called the capacitive reactance of ac signal,it is associated with the frequency of the ac signal and capacitance.Capacitive reactance XC = 1/2 PI c f (f is the frequency of the ac signal,capacitance c said) is commonly used in telephone with electrolytic capacitor,the kinds of ceramics capacitors,SMD capacitors,monolithic capacitors,tantalum capacitors,polyester capacitors,etc. brake rotor 2,capacitance recognition methods: identification method of capacitance and resistance identification method of basic same,straight standard method,three kinds of color standard method and standard method. 

The basic unit of capacitance with ferrari (F),according to other units include: milli single phase electric motor method (mF),micro method (uF),sodium (nF),leather (pF).Among them: 1 q = 10 3 mm = 10 6 micro method = 9,10 = 10 12 leather method of large capacity capacitor on capacitance directly to mark its capacity values,such as 10 uF / 16 v capacity small capacitance of its capacity value with letters or Numbers on the capacitance letter notation: 1 m = 1000 uF p2 = 1.2 PF 1: n = 1000 PF digital wholesalemotor.blogspot.com representation commonly used three figures show that the size,two significant figures,said before the third digit ratio. Such as: 102 said 10 x 102 = 1000 pf pf said 22 224 x 224 = 0.22 uF pf 3,the capacitance error table F G J K L M allowed error of plus or minus 1% plus or minus 2% plus or minus 5% plus or minus 10% plus or minus 15% plus or minus 20%,such as: a ceramics capacitors for 104 J said capacity of 0. 1 uF,the error of plus or minus 5%.
