What Is a Ceramic Capacitor?

Ceramic capacitors (ceramic capacitors) are also called ceramic capacitors or monolithic capacitors. As the name suggests, ceramic capacitors are capacitors whose dielectric material is ceramic. According to the different ceramic materials, it can be divided into two types: low-frequency ceramic capacitors and high-frequency ceramic capacitors. Classified according to the structure, it can be divided into wafer capacitors, tubular capacitors, rectangular capacitors, chip capacitors, through-capacitors and so on.

Its shape is mostly sheet-shaped, and it also has tube and round shapes.

Ceramic materials have superior electrical, mechanical, and thermal properties, and can be used as capacitor dielectrics, circuit substrates, and packaging materials.
There are many methods for naming rectangular capacitors for rectangular chip ceramic capacitors. The common ones are:
(1) Named Series of Rectangular Capacitors with Same Rectangular Chip Ceramic Capacitors
Code temperature characteristics capacity error pressure-resistant packaging CC3216 CH 151K 101WT
(2) American Predsidio company series code temperature characteristic capacity error packaging CCl206 NPO151JZT
Same as chip resistors, the letters in the above code represent rectangular chip ceramic capacitors, and the 4-digit number indicates its length and width, and its thickness is slightly thicker, generally 1 ~ 2mm.
Similar to chip resistors, the first two digits of the capacity represent the effective number, and the third digit represents the number of zeros after the effective number. The unit is pF. For example, 151 indicates 150pF, and 1p5 indicates 1.5pF.
The meaning of the letters of the error part: C is ± 0.25pF, D is ± 0.5pF, F is ± 1 pF, J is ± 5pF, K is ± 10pF, M is ± 20pF, and I is -20% to 81%. [5]
