Capacitor plus ceramic chip

What are the different types of multilayer ceramic chip capacitors?

Multilayer ceramic chip capacitors used extensively in electronic devices can be divided into two major categories according to their type of dielectric, namely (1) low dielectric constant type, and (2) high dielectric constant type.

What are the different types of ceramic chip capacitors?

There are two types of multilayer ceramic chip capacitors: low (Class I) and high (Class II) dielectric constant types, differentiated by their temperature characteristics.

What is a ceramic disc capacitor?

A ceramic disc capacitor. (Image: Wikimedia / Elcap.) Ceramic capacitors are available in disc packages with radial leads. Surface mount multilayer ceramic chip (MLCC) capacitors are very popular. The stacking of very thin layers permits MLCC capacitors to provide relatively large values of capacitance at lower voltages.

Why are multilayer ceramic chip capacitors so thin?

Consequently, multilayer ceramic chip capacitors require advanced nanotechnologies. TDK has achieved the utmost in thinness by embracing technologies to micronize and disperse dielectric and nickel particles that form the internal electrodes at nanometer scales. Dielectric sheets are thin, brittle, and easily fractured.

What is a multilayer ceramic chip capacitor (MLCC)?

MLCCs are made of alternating layers of metallic electrodes and dielectric ceramic, as shown in figure 1 below. Figure 1: Construction of a multilayer ceramic chip capacitor (MLCC), 1 = Metallic electrodes, 2 = Dielectric ceramic, 3 = Connecting terminals

Can a multilayer ceramic chip capacitor leak current?

Because multilayer ceramic chip capacitors have a high insulation resistance, leak current does not present a problem in normal applications. However, when the rated voltage is exceeded and the applied voltage is increased further, the capacitor will be subject to insulation breakdown at some point.
