Ceramic Disc Capacitor Schematic

Hence the value of the capacitor above is 47000 pf 5.

Ceramic disc capacitor schematic.

When the first two numbers are multiplied with the multiplier the. Smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small disc type. Mlccs are the most produced capacitors with a quantity of approximately 1000 billion devices per year. The types of ceramic capacitors most often used in modern electronics are the multi layer ceramic capacitor otherwise named ceramic multi layer chip capacitor mlcc and the ceramic disc capacitor.

Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors. When the ceramic capacitor are layered multiple times it becomes mlcc. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. Method of finding the value meaning of codes of capacitor.

An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. It is a very small and fixed value capacitor.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Ct7 ac disc ceramic capacitor the capacitors are available for color tv sets and the circuits linked astride the power lines by passing antenna coupling and switch surge suppressor in any other electronic equipment. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. Different types of ceramic capacitors.

Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more. The ceramic disc capacitor is pretty much the standard type used in the tone control circuit. The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads. If you are new to capacitor codes then the best way to start is with a chart because that way you can see the arrangement of the code.

This type of capacitor is very inexpensive to build and most look very much like figure 1. As per the diagram. Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads. The ceramic capacitance also designed for high voltage devices and the voltage rating can go up to 100kv.
