Ceramic Capacitor Single Layer Vs Multilayer

The typical temperature range for ceramic capacitors is 40 to 85 c or 125 c where their capacitance varies about from 5 to 40 having a sweet spot around 5 to 25 c.

Ceramic capacitor single layer vs multilayer. Avx offers a complete line of single layer ceramic slc capacitors with dielectric constants ranging from 14 np0 to greater than 30 000 x7r. Multi layer ceramic smd capacitors are generally a superset of the older disc capacitors. Ceramic materials are the most widely used dielectrics in modern discrete capacitors with ceramic dielectric material providing insulation layers for a wide range of both single layer ceramic capacitors slccs and multilayer ceramic capacitors mlccs. Advantages of mlcc include.

Product offerings include standard slc s with without borders in all dielectric families. Multilayer ceramic capacitors mlccs are generally the capacitor of choice for applications where small value capacitances are needed. They are used as bypass capacitors in op amp circuits filters and more. Small parasitic inductance give better high frequency performance compared to aluminum electrolytic capacitors.

If you needed a rugged part or a part that could not be surface mounted you would choose the disc i know you can get leaded multilayer ceramics but its a disappearing market. A standard multi layer ceramic capacitor has many opposing electrode layers stacked inside connected with two outer terminations. The choice would come down to things like that. It is constructed like a standard two terminal mlcc out of the stacked ceramic layers with an additional third set of shield electrodes incorporated.

The x2y ceramic chip capacitor however is a 4 terminal chip device. Also i d look at the schematic carefully and see how that capacitor is used. Single layer left and multilayer right there are two main types of ceramic capacitors. 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.

A single wafer of ceramic is going to take more abuse than a stack of thin layers of ceramic. Slc s with double sided borders are now available in most dielectrics. Overview tecdia chip capacitors are normally constructed as square chips for single values and binary capacitor arrays and in rectangular shapes for capacitor row arrays and custom designs. This permits a broad range of capacitance values.

Ceramic capacitors are brittle and sensitive to thermal shock so precautions need to be taken to avoid cracking during mounting especially for high capacitance large sizes. Class 1 capacitors are more accurate and stable over a larger range of temperatures while class 2 capacitors offer more volumetric efficiency more capacitance per unit volume.
