Ceramic Capacitors HF use

Ceramic capacitors are suitable for moderately high-frequency work (into the high hundreds of megahertz range, or, with great care, into the low gigahertz range), as modern ceramic caps are fairly non-inductive compared to the other major classes of capacitors (film and electrolytic). Capacitor technologies with higher self-resonant frequencies tend to be expensive and esoteric (typically, mica or glass capacitors).

Ceramic Capacitors Knowledge

A ceramic capacitor is a two-terminal, non-polar device. The classical ceramic capacitor is the "disc capacitor". This device pre-dates the transistor and was used extensively in vacuum-tube equipment (e.g., radio receivers) from c.a 1930 through the 1950s, and in discrete transistor equipment from the 1950s through the 1980s. As of 2007, ceramic disc capacitors are in widespread use in electronic equipment, providing high capacity & small size at low price compared to other low value capacitor types.

Ceramic capacitors offer a broad range of size vs. performance tradeoffs and are easily the most popular in numbers sold. Ceramic capacitors are available from < 1 pF to 1000s of uF.

Ceramic Capacitors Pros: The main virtue of ceramic capacitors are their relatively high dielectric constants. This can vary from C0G with a K of up to 60, which has excellent electrical properties but is relatively large and expensive, to ceramics with Ks in the tens of thousands but with very poor electrical properties. Large- value ceramics can replace electrolytic capacitors in high-frequency applications like switch-mode power supplies because of their lower ESR. Ceramic capacitors are especially suitable for surface mounting due to their heat resistance, mechanical integrity, and the ability to make them in very small packages at low cost, for portable equipment. This has greatly added to their usage. To some extent ceramics are slowly displacing other types of capacitors.

Ceramic Capacitors Cons: Low breakdown voltage means that the low-K ceramics (Class 1), the ones with the good electrical properties, have poor volumetric efficiency, and are usually found only in small values. High-K ceramics (Class 2 and higher) have poor electrical properties, which are highly dependent on temperature, voltage, and frequency, plus a significant aging rate. Unlike many other capacitors, ceramics have no self-healing mechanism. This means that manufacturers must maintain a high level of quality control over the dielectric. Ceramics are most cost affective in small sizes at present. Very large ceramics are a bit of a challenge, especially in SMD.
