In the current electronic components market, there are many kinds of capacitors, and there are also many differences in function, Cucab takes you to understand one of the capacitors, ceramic capacitors. To know what are ceramic capacitors?
1. Mis on keraamiline kondensaator
Keraamilisi kondensaatoreid nimetatakse tavaliselt portselanist dielektrilisteks kondensaatoriteks või monoliitkondensaatoriteks. Nimetusest lähtuvalt on keraamilised dielektrilised kondensaatorid kondensaatorid, mille andmekandja on keraamiline. Vastavalt erinevatele keraamilistele materjalidele võib need jagada kahte kategooriasse: madalsageduslikud ja kõrgsageduslikud. Struktuurilise vormi järgi võib neid liigitada ümmarguseks kiibiks, toruks, ristkülikukujuliseks, helvesteks, läbistavaks ja paljudeks teisteks. Keraamilistel materjalidel on suurepärased elektrilised, mehaanilised ja termilised omadused ning neid saab kasutada kondensaatorite dielektriliste, vooluahela substraatide ja pakkematerjalidena.
Millised on keraamiliste kondensaatorite omadused?
With the development of electronic technology, the requirements for working voltage of electronic circuits are getting lower and lower, from the original 5V to the current 3V and some lower 15V, on the other hand, the miniaturization of power supply needs small and large capacity products to replace the large volume of aluminum electrolytic capacitors. In order to meet the development and application of these low voltage and large capacity MLCCs, relaxation type high dielectric materials with relative dielectric constant 1 to 2 times higher than BaTiO3 have been developed.

In the process of developing new products, three key technologies have been developed at the same time, namely, the technology of making ultra-thin raw chip powder dispersion, the technology of improving raw chip film formation, and the technology of matching the shrinkage rate of inner electrode and ceramic raw chip. Recently, Matsushita Electronic Components of Japan has successfully developed a large-capacity MLCC with a capacity of approximately 100 μF and a high withstand voltage of 25 V. This product can be used in the power supply circuit of liquid crystal displays (LCDs).
