Capacitance common sense

• By Media Category:

　　   Ceramics, mica, paper, film, electrolytic capacitors

• Identifying capacity of the capacitor:

　　   Recognition of the capacitor division direct standard method, three kinds of color standard method several standard method.

   a, direct standard method is the nominal value of the capacitance of the capacitor is represented with the number and the unit body: such as: 220MF showing 220UF; .01UF represents 0.01UF;

         R56UF represents 0.56UF; 6n8 represent 6800PF.

　　    b, not standard unit of digital representation. Wherein the four-digit with a valid number, typically the PF, and its capacity electrolytic capacitor was UF.

　　　　  Such as: 3 represents 3PF; 2200 represents 2200PF; 0.056 represents 0.056UF;

　　    C, the digital representation: the digital representation is generally a three capacity size, the first two significant figures, showing the third power of 10 times.

　　　　  The 102 represents a 10 * 102 = 1000PF; 224 represents a 22 * ​​104 = 0.2UF

　　　d, showing the main characteristics of the capacitor with a color wheel or color point. Color scale the same capacitor with a resistor.

• Capacitor deviation glyph:

　　　a、 +100%-0--H；

　　　b、+100%-10%--R、

　　　c、+50%-10%--T、

　　　d、+30%-10%--Q、

　　　and 50% -20% + - S,

　　　f、+80%-20%--Z。

• The main performance of the capacitor

　　　a, the capacitance of the capacitor (i.e., the charge storage capacity);

　　　b, voltage value (RMS means the maximum DC voltage or AC voltage maximum capacitance long time reliable operation in the rated temperature range);

　　　c, temperature values ​​(represented by capacitance can withstand a maximum operating temperature.).
