Ceramic Disc Capacitor Schematic

This type of capacitor is very inexpensive to build and most look very much like figure 1.

Ceramic disc capacitor schematic.

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. When the first two numbers are multiplied with the multiplier the. Method of finding the value meaning of codes of capacitor. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. Different types of ceramic capacitors. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s.

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. 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.

When the ceramic capacitor are layered multiple times it becomes mlcc. As per the diagram. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. 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. Suits for pulse circuit oscillation and temperature circuit. Hence the value of the capacitor above is 47000 pf 5. 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. It is a very small and fixed value capacitor. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. Smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small disc type.
