Can ceramic capacitors replace multilayer capacitors?

Yes, as long as the capacity is the same, there is no problem.

Multilayer capacitors are also known as porcelain dielectric capacitors, which have the advantages of large capacity and small size, and have strong high temperature resistance. Comparatively speaking, it is one of the many advantages of capacitor types. So, what are the functions of monolithic capacitors?

The role of a monolith capacitor can be summarized into four roles. The first is energy storage exchange, which is directly connected to the communication, and the second is frequency discrimination filtering.

Finally, there is the surge.

Suppression of voltage. The so-called energy storage exchange is mainly through its charging and discharging process to generate and discharge an electric energy.

The phenomenon of electrification at both ends is reflected through the regular steering of the communication. Therefore, in the circuit, it can be connected in parallel with other components to make the AC pass, while the DC is blocked, playing the role of a side collapse. In AC circuits, the multilayer capacitor is charged and discharged with the change of polarity of the input signal, so that the circuit connecting the two ends of the multilayer capacitor behaves in a conductive state and plays a coupling role.

In addition, it is the role of frequency discrimination filtering. In an AC circuit, for a multi-frequency mixed signal, we can use a monolith capacitor to separate its parts, and generally speaking, we can use a reasonable circular capacitance.

The monolith capacitor filters out most of the low-frequency signal. This is dominated by high-frequency or ultra-high-frequency monolithic capacitors.

The role of multilayer capacitors should not be underestimated, especially in terms of their surge voltage suppression. Since the monolith capacitor is an energy storage element, it can remove those short surge pulse signals in the circuit.

It can also absorb excess energy generated by voltage fluctuations in the circuit. The filtering is mainly based on high-frequency products.

Ceramic capacitors and multilayer capacitors are capacitors with high frequency of use, which have attracted everyone's attention and favor in the development process.

There are certain differences between these two capacitors from different perspectives, and the next thing I want to analyze is the difference between the two.

You can choose the right capacitor according to your advantages.

The porcelain capacitor is made of thin porcelain on both sides of the metal film.

Its advantages are small size, high withstand voltage, low voltage, high frequency (there is a high-frequency capacitor), relatively speaking, there must be advantages and disadvantages, and the disadvantage of porcelain capacitors is fragile! Low capacity.

It is often used in high-frequency**, resonance, decoupling, and audio.

Porcelain capacitors are molded with ceramic powder and then sintered.

Ceramics are divided into class I porcelain, class II porcelain, class III porcelain) monolithic porcelain single-layer structure, generally button size with two pins.

Because of the single-layer structure, ceramic capacitors generally do not have a large capacity but a high voltage.

Each single layer is equivalent to a capacitor, and dozens of layers are equivalent to dozens of capacitors in parallel.

So the MLCC capacity is very large, but the voltage is not high.

It is generally surface-mounted.

The monolith capacitor is smaller than CBB, and the other CBB is often used in analog and digital circuit signal bypass, filtering, and audio.

The monolith capacitor is a complete variant of the MLCC, on which two leads are soldered and encapsulated with epoxy resin.

The capacitance of the porcelain tile is small in size, the temperature coefficient is wide, the dielectric loss is small, the leakage is small, and the moisture resistance is small.

Disadvantages: small capacity, strong machinery or poor stool mess.

The multilayer capacitor has a large capacitance and is suitable for low frequencies.

Ceramic capacitors are suitable for high frequencies.

can be replaced. The above content is to look at the porcelain electrocoarse capacitance and monolith capacitance from multiple angles.

Through the comparison of the two, do you know which capacitor is more advantageous?

It is good to do your homework when choosing any type of capacitor, and you will not waste time on the selection.

In less demanding applications, these capacitors are interchangeable.

Each capacitor has its own characteristics:

The monolith capacitance is relatively stable, the temperature drift coefficient is small, the capacitance value can be 1uf, the life is long, the equivalent DC resistance is small, and it is slightly more expensive.

The high-frequency characteristics of the ceramic capacitor are good, but the maximum capacitance value can only be achieved.

Ceramic capacitors are also a type of ceramic capacitors.

The following is the identification method of the capacitor withstand voltage representation of the vertical company: Note: The character ** description English letters indicate the significant number.

Arabic numerals before English letters indicate orders of magnitude. 1 means 101 is 10, 2 means 10 is 100, and 3 means 10 is 1000. Example:

2J222J means withstand voltage 630V capacity 2200p accuracy 5% In example: 2G473K means withstand voltage 400V capacitor capacitance accuracy 10%.

A 1UF capacitor is connected to 220V and has about 60mA current! You just have to use the proportional calculation!

It can replace a lot, such as CBB capacitors, porcelain capacitors, mica capacitors, as long as the capacitance value is the same, and the withstand voltage value is greater than or equal to the replacement capacitor (it is recommended not to replace it with polar capacitors), but it is recommended not to replace high-precision circuits, or replace them after careful demonstration.
