Ceramic Capacitor Voltage

Is it ok to use ceramic capacitors over the rated voltage.

Ceramic capacitor voltage.

How to read a ceramic capacitor value. 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. Remember that capacitors are storage devices. Meaning they hold a certain size charge 1µf 100µf 1000µf etc at a certain.

The rated voltage availability of the ceramic capacitor is around 2v and above. Many hobbyists especially in the field of robotics are familiar with ceramic disc capacitors used across brush dc motors to minimize rf noise. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. Ceramic capacitors exhibit low parasitics and excellent emi filtering capabilities.

In a multilayer configuration they display high capacitance values and various voltage ratings over a wide temperature range. This is a mechanism of decrease in the capacitance after applying dc voltage. High voltage ceramic capacitor snap in screw terminal aluminum electrolytic capacitors high temperature film capacitor high temperature mica capacitors and high temperature tantalum capacitor 155c 175c 200c. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

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. When the ceramic capacitor has 3 digits like 101 102 103 etc then the values indicate that they are to be measured in picofarad. 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.
