Ceramic Disc Capacitor
The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a condenser or condensator. ( Click here for wide range of Capacitors).
The capacitor is a passive component that can store a charge (Q). This charge (Q) will be a product of the value of capacitance (C) and the voltage (V) applied to it. The value of the capacitance and Voltage of a capacitor will be mentioned on its label.
Hence the amount of charge a capacitor can be found using the value of Voltage (V) and Capacitance (C) of the capacitor.
C = Q×V
The value of a ceramic capacitance will not be directly mentioned on the capacitor. There will always be a three-digit number followed by a variable; let’s learn how to identify the value using these numbers. Consider the following capacitor.
these three digits are split into two digits and the third one is the multiplier. In this case, 68 is the digit and 3 is the multiplier. So 68 should be multiplied with 10^3. Simply put it is 68 followed by 3 zeros. Hence the value of this capacitor will be 68000 pF. Notice the unit should always be pF. Similarly, a capacitor with 220 code means it is 22 Pico farad since 10^0 is 0.
The voltage rating of the capacitor can be found by using the line under this code. If there is a line then the voltage value is 50/100V if there is no line then it is 500V.
The most commonly used capacitor values along with their conversion in Pico Farad, Nano Farad, and microfarad is given below.
|Code||Picofarad (pF)||Nanofarad (nF)||Microfarad (uF)|
The Ceramic Capacitors have no polarity. Meaning they can be connected in any direction. They are breadboard friendly and can be easily used on a perf board also. The symbol for a ceramic capacitor is just two plain lines as shown above since they do not have any polarity.
