Blue ceramic capacitor withstand voltage

The basic unit usage of the capacitor is (F), and other units are: millifarad (mF), microfarad (μF)/mju:/, nanofarad (nF), and picofarad (pF). Where: 1 Farad = 1000 millifarads (mF), 1 millifarad = 1000 microfarads (μF), 1 microfarad = 1000 nanofarads (nF), 1 nanofarad = 1000 picofarads (pF)

1. The capacity of the capacitor with large capacity is directly indicated on the capacitor, such as 10 μF/16V;

2. The capacity of a capacitor with a small capacity is represented by a letter or a number on the capacitor;

Letter notation:

1m=1000μF

1P=1pF (eg 470P=470pF)

1P2=1.2PF

1n=1000PF;

In addition, there is an error value.

K.M.J represents the capacitance error value

K represents the capacity deviation ±10%

M stands for deviation ±20%

J stands for deviation ±5%

That is to say, for example, the capacity of 1000PF, the tolerance is between 1000+1000*10% and 1000-1000*10%. Different deviation effects are also different. Usually, the deviation from many cases can replace the large deviation.

103 is 10*10^3=10000pf=0.01uF

The rated voltage of the blue ceramic capacitor is usually 1000V, 2000V, and can be made 1KV-12KV.
