Ceramic Disc Capacitor Uses

The area of a ceramic disc or dielectric and spacing between the silver electrodes also determines the capacitance of the ceramic disc capacitor.

Ceramic disc capacitor uses.

Ceramic capacitors can also be used as a general purpose capacitor because of their non polarity and are available in a large variety of capacitances voltage ratings and sizes. Ceramic capacitors are available in small values such as in micro milli nano pico farads. The ceramic disc capacitor is pretty much the standard type used in the tone control circuit. Characteristics precision and tolerances.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. The values of the ceramic capacitors are typically between the 1nf and 1µf and. Also i d look at the schematic carefully and see how that capacitor is used. Ceramic capacitor is made up of ceramic material which acts as a dielectric material for it.

Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. There is really nothing the old 100 nf disc capacitor can do that a modern 100 nf smd cap can t do within their voltage ratings. Multi layer ceramic smd capacitors are generally a superset of the older disc capacitors. The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s.

The main disadvantage of using ceramic disc capacitor is its high capacitance change with slight change in temperature. Ceramic disc capacitors are used across brush dc motors to minimize rf noise. The capacitors are widely used in all sorts of electronic instruments and high voltage by passing or coupling circuit. Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors.

The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. The multilayer ceramic capacitors are prepared by using the surface mounted smd technology and they are smaller in size therefore it is used widely. When the ceramic capacitor are layered multiple times it becomes mlcc. This type of capacitor is very inexpensive to build and most look very much like figure 1.

An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. A ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Cc81 high frequency and high voltage ceramic disc capacitor low df stable capacitance. Capacitors store energy in the dielectric not in the conductive.
