How are multilayer ceramic chip capacitors made?

Multilayer ceramic chip capacitors are manufactured by integrating a variety of core technologies. Techniques for making the dielectric and internal electrode sheets thinner are especially key to miniaturization and achieving higher capacitance.

What is a multilayer ceramic capacitor?

The multilayer ceramic capacitor (MLCC), which is one of them, is the most significant passive element capable of storing and releasing electrical charge. For resonant circuit applications, MLCCs provide excellent stability and low losses, as well as great volumetric efficiency for buffer, by-pass, and coupling applications .

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.

How does a ceramic chip capacitor work?

Dozens, hundreds, or more than a thousand of these sheets are stacked together, pressed, cut into chip size, and sintered in a furnace—creating hardened, ceramic chips. Finally, paste material that forms the external electrodes is applied on both ends, sintered and plated—and a multilayer ceramic chip capacitor is born.

Where are ceramic capacitors made?

Comprising pressed ceramic materials with a single thick ceramic layer coated with silver metallized electrodes, these capacitors are primarily manufactured in Japan, Taiwan and China and find use in high voltage television flyback transformers and specialized defense electronics power supplies.

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.
