Ceramic Disc Capacitor Schematic

The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads.

Ceramic disc capacitor schematic.

Method of finding the value meaning of codes of capacitor. Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads. Smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small disc type. The ceramic disc capacitor is pretty much the standard type used in the tone control circuit.

This type of capacitor is very inexpensive to build and most look very much like figure 1. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors. 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.

Different types of ceramic capacitors. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes.

Mlccs are the most produced capacitors with a quantity of approximately 1000 billion devices per year. As per the diagram. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. It is a very small and fixed value capacitor.

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. The ceramic capacitance also designed for high voltage devices and the voltage rating can go up to 100kv. Hence the value of the capacitor above is 47000 pf 5. 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.

Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. Suits for pulse circuit oscillation and temperature circuit. An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. 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.
