1, straight standard method: the number and unit symbols directly marked. Such as 01uF that 0.01 micro-law, some capacitors with "R" that the decimal point, such as R56 said 0.56 micro-law.
2, the text symbol method: the use of digital and text symbols to represent the regular combination of capacity. Such as p10 said 0.1pF, 1p0 said 1pF, 6P8 said 6.8pF, 2u2 said 2.2uF. 3, color standard method: with color ring or color point that the main parameters of the capacitor. The color of the capacitor is the same as the resistance
Capacitor Bias Symbol:
+ 100% -0 - H, + 100% -10% - R, +50% -10% - T, +30% -10% - Q, +50% -20% - S, 80% -20% - Z
Common Capacitors:
Electrolytic capacitors, tantalum electrolytic capacitors, film capacitors, ceramic capacitors, monolithic capacitors, paper capacitors, fine-tuning capacitors, ceramic capacitors, glass glaze capacitors, mica and polystyrene dielectric capacitors.
Simple Test Method for Capacitor Capacity
One voltmeter and ammeter should be used as far as possible with high precision magnetic or electrical instrument. Turn on the power, as soon as possible (1-2S) record the value of the instrument. When the power frequency is 50HZ, use the following formula to obtain the capacitance of the measured capacitor.
C = 3183 I / U where C ---- capacitance of the capacitor under test, μFI ----- ammeter reading, A;

U - voltmeter reading, V
