Ceramic Disc Capacitor Types

A ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

Ceramic disc capacitor types.

There are two classes of ceramic capacitors available today. The most widely preferred types of this ceramic capacitors are. There are a few types of plastic film capacitors including mylar polycarbonate polyester and. Different types of ceramic capacitors.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads. 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 two common types of ceramic capacitors are multilayer ceramic capacitor mlcc and ceramic disc capacitor.

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 are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads. It is possible to manufacture them by making the silver coating on the sides of the discs.

As the name indicates it is in the form of a disc with the two leads emanating from the bottom of the encapsulation. These are in the shape of discs. Where this coating is considered to be as electrodes and the disc is made of ceramic considered to be as dielectric. The multilayer ceramic capacitors are prepared by using the surface mounted smd technology and they are smaller in size therefore it is used widely.

There are several types of ceramic capacitor that can be obtained. Ac line rated ceramic disc capacitors class x1 400 vac class y4 125 vac. Class 1 and class 2. This type of capacitor is very inexpensive to build and most look very much like figure 1.

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. Characteristics precision and tolerances.
