Monolithic capacitor is another name for multi-layer ceramic capacitor. The English name is monolithic ceramic capacitor or multi-layer ceramic capacitor, or MLCC for short. According to the materials used, it can be divided into three types. Namely, temperature compensation type NPO dielectric, high dielectric constant type X7R dielectric, semiconductor type Y5V dielectric. Ceramic capacitor is an electronic component, mainly made of ceramic material isolation meson, is an insulator, it is coated with a layer of metal film on the ceramic surface, and then sintered at high temperature as an electrode capacitor. It is commonly used as loop, bypass and pad capacitors in high stable oscillation circuits. Chip capacitors are divided into four categories, namely, in-line ceramic capacitors/chip capacitors (single-layer structure), chip ceramic capacitors, single stone capacitors (multi-layer structure), and high voltage ceramic capacitors.
Monolithic capacitance is larger than the general porcelain dielectric container (10pF~10μF), and large capacitance, small volume, high reliability, stable capacitance, high temperature resistance, good insulation, low cost advantages, so it has been widely used. Monolite capacitors can replace not only mica capacitors and paper capacitors, but also some tantalum capacitors. They are widely used in small and ultra-small electronic devices such as LCD watches and micro-instruments. For some occasions is not strict, this two kinds of capacitance can be interchangeable with the rigorous nature is not to replace of occasions, after all, for no capacitance in its characteristics and performance are different monolithic capacitor is stable, ask small temperature drift coefficient, capacitance value can be 1 uf, long life, the equivalent dc resistance is small, the price is a bit expensive, However, the high frequency characteristic of ceramic chip capacitor is good, and the single capacitance value can only achieve 0.1uF.
Monolite capacitor and ceramic capacitor these two different capacitors also have something in common, that is, there is no positive or negative, only electrolytic capacitors have a positive or negative, and for monolite capacitor, its disadvantage is that the temperature coefficient is very high, do oscillator steady drift people can not stand, And if replaced with polyester capacitor will better monolithic capacitor has a large capacity of power, small volume, high reliability, stable capacitance, resistance to high temperature and wet resistance good, etc., while ceramics capacitors have stronger resistance to high pressure and insulation, but not with the capacity of the monolithic capacitor, so the demand for the occasion of the large capacity and equipment, choose monolithic capacitor is a reliable choice, If the ceramic capacitor is selected, the operation will be slowed down or other faults due to insufficient capacity. This is the introduction of monolite capacitor and porcelain capacitor. In fact, monolite capacitor is also called porcelain dielectric capacitance. There is only one word difference between monolite capacitor and porcelain capacitor, but there is also a big difference.
