Ceramic Disc Capacitor Vs Multilayer

This multi layer ceramic capacitor.

Ceramic disc capacitor vs multilayer.

They are rated for wvdc to 250 v dc. Different types of ceramic capacitors. The application typically dictates the best choice of capacitor type multilayer ceramic capacitor mlcc aluminum electrolytic polymer or tantalum to use in the design. Generally speaking while electrolytic capacitors provide the largest capacitance they suffer significant degradation in capacitance and leakage current at higher temperatures and frequencies.

The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s. An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. If by monolithic you mean the multi layer chip caps sometimes labled mlcc that s what all the high density ceramic caps are. 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.

This type of capacitor is very inexpensive to build and most look very much like figure 1. Also i d look at the schematic carefully and see how that capacitor is used. The same company s 700a and 700b series of porcelain and ceramic multilayer capacitors also provide the temperature stable characteristics of npo dielectric materials in multilayer configurations. The traditional disc caps are basically just a slab of ceramic with plate on each side radial leads attached and dipped in epoxy or maybe ceramic for coating.

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. Multi layer ceramic smd capacitors are generally a superset of the older disc capacitors. The ceramic disc capacitor is pretty much the standard type used in the tone control circuit. Mlccs are the most produced capacitors with a quantity of approximately 1000 billion devices per year.

Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. With capacitance values of 0 1 to 1000 pf. The ceramic capacitor uses a thin ceramic layer as the dielectric medium whereas the electrolytic capacitor uses an ionic liquid as one of the sheets of the capacitor. Ceramic capacitors and electrolytic capacitors are two main types of capacitors that are widely used in electrical and electronic components.
