Ceramic Capacitor Voltage
Many hobbyists especially in the field of robotics are familiar with ceramic disc capacitors used across brush dc motors to minimize rf noise.
Ceramic capacitor voltage. How to read a ceramic capacitor value. Is it ok to use ceramic capacitors over the rated voltage. In a multilayer configuration they display high capacitance values and various voltage ratings over a wide temperature range. Ceramic capacitors exhibit low parasitics and excellent emi filtering capabilities.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. When the ceramic capacitor has 3 digits like 101 102 103 etc then the values indicate that they are to be measured in picofarad. Remember that capacitors are storage devices. The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store.
When the first two numbers are multiplied with the multiplier the. Meaning they hold a certain size charge 1µf 100µf 1000µf etc at a certain. Ceramic capacitors can also be used as a general purpose capacitor since they are not polarized and are available in a large variety of capacitances voltage ratings and sizes. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
Method of finding the value meaning of codes of capacitor. For your information in temperature compensation capacitors ch c0g characteristics etc capacitance doesn t change because paraelectric ceramic is used as its main material and that gives the dc voltage characteristic to the capacitors. The rated voltage availability of the ceramic capacitor is around 2v and above. This is a mechanism of decrease in the capacitance after applying dc voltage.
A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.
