Ceramic Capacitance Reading Method (2)

Capacitor values of large capacity are directly indicated on the capacitor, such as 10 μF/16V; 2. Capacitance values of capacitors with small capacity are represented by letters or numbers on the capacitors;

Letter notation: 1F=10^6uF=10^12pF1F=1000000μF1m=1000μF 1P=1pF (eg 470P=470pF) 1P2=1.2PF 1n=1000PF;

Digital notation: The three-digit representation is also called the digital representation of the capacitance. The first two digits of the three digits are the significant digits of the nominal capacity, and the third digit represents the number of zeros following the significant digit, all of which are in pF.

Such as:

102 denotes a nominal capacity of 10×(10^2)pF=1000pF=0.001 μF; 103 denotes a nominal capacity of 10×(10^3)pF=10000pF=0.01 μF; 104 denotes a nominal capacity of 10×(10) ^4) pF=100000pF= 0.1 μF; 105 indicates a nominal capacity of 10×(10^5) pF=1000000pF=1 μF; 470 indicates a nominal capacity of 47 pF; and 223 indicates a nominal capacity of (22×(10^) 3)) pF (ie 22000pF); 224 indicates nominal capacity is (22 × (10 ^ 4)) pF (ie 220000pF) = 0.22uF safety capacitor and high-voltage ceramic capacitor capacity error with symbols F, G, J, K , L, M to indicate that the allowable errors correspond to ±1%, ±2%, ±5%, ±10%, ±15%, ±20%, respectively.
