Monolithic capacitors, ceramic capacitors, and ceramic capacitors are all common capacitor components. Monolithic capacitors are relatively stable, have a small temperature drift coefficient, a capacitor value of 1uF, a long life, and a small equivalent DC resistance.
The high-frequency characteristics of ceramic capacitors are good, but the maximum capacitance value can only be 0.1uF. Ceramic capacitors are also a type of ceramic capacitors. Ceramic capacitors are generic terms. Porcelain capacitors are capacitors made of ceramic material as a dielectric, coated with a metal film on the surface of the ceramic, and then sintered at high temperature as an electrode. It is usually used in high-stability oscillation circuits as circuits, bypass capacitors, and pad capacitors. Capacitors with a small positive capacitance temperature coefficient are used in highly stable oscillating circuits as circuit capacitors and pad capacitors. Low-frequency ceramic dielectric capacitors are limited to bypass or DC-blocking in circuits with low operating frequencies, or where stability and loss requirements are not high (including high frequencies). Such capacitors are not suitable for use in pulsed circuits because they are prone to breakdown by pulsed voltages.
For ceramic capacitors, a high dielectric constant capacitor ceramic (barium titanate-titanium oxide) is extruded into a circular tube, a wafer, or a disk as a medium, and silver is plated on the ceramic as an electrode by infiltration. It is divided into two types of high-frequency porcelain and low-frequency porcelain. Capacitors with a small positive capacitance temperature coefficient are used in highly stable oscillating circuits as circuit capacitors and pad capacitors. Low-frequency ceramic dielectric capacitors are limited to bypass or DC-blocking in circuits with low operating frequencies, or where stability and loss requirements are not high (including high frequencies). Such capacitors are not suitable for use in pulsed circuits because they are prone to breakdown by pulsed voltages.
Porcelain capacitor
The difference between ceramic capacitors, monolithic capacitors, and ceramic capacitors
Ceramic capacitor is a capacitor made of ceramic material as a dielectric, coated with a metal thin film on the ceramic surface, and then sintered at high temperature as an electrode. It is usually used in high-stability oscillation circuits as circuits, bypass capacitors, and pad capacitors. There are two types of ceramic capacitors: high-frequency ceramic and low-frequency ceramic. Capacitors with a small positive capacitance temperature coefficient are used in highly stable oscillating circuits as circuit capacitors and pad capacitors. Low-frequency ceramic dielectric capacitors are limited to bypass or DC-blocking in circuits with low operating frequencies, or where stability and loss requirements are not high (including high frequencies). Such capacitors are not suitable for use in pulsed circuits because they are prone to breakdown by pulsed voltages.
Advantages: stable, good insulation, high voltage resistance
Disadvantages: relatively small capacity
Monolithic capacitor
The difference between ceramic capacitors, monolithic capacitors, and ceramic capacitors
The monolithic capacitor is another name for the multilayer ceramic capacitor. The English name is monolithic ceramic capacitor or multi-layer ceramic capacitor, referred to as MLCC, which can be divided into three types according to the materials used.
The first type is the temperature-compensated NPO dielectric. This capacitor has the most stable electrical performance. It basically does not change with temperature, voltage, and time. It is an ultra-stable, low-loss capacitor material type. High frequency, UHF, VHF circuits.
The second type is a high dielectric constant type X7R dielectric. Because X7R is a ferroelectric, it can produce capacitors with a larger capacity than NPO dielectrics. The performance of this capacitor is relatively stable. With the change of temperature, voltage and time, its unique performance changes are not significant. It belongs to the type of stable capacitor material. Frequency circuit.
The third type is a semiconductor-type Y5V dielectric. This capacitor has a high dielectric constant and is often used to produce large-capacity capacitors with a large specific capacity and a high nominal capacity. However, its capacity stability is worse than X7R, and its capacity and loss are more sensitive to test conditions such as temperature and voltage. It is mainly used in the oscillation, coupling, filtering, and bypass circuits of electronic complete machines.
Features: good temperature characteristics and good frequency characteristics. Generally, as the frequency rises, the capacitance decreases. The monolithic capacitance decreases less and the capacity is more stable.
Ceramic capacitors

For ceramic capacitors, a high-dielectric constant capacitor ceramic (barium titanate-titanium oxide) is extruded into a circular tube, a wafer, or a disk as a medium, and silver is plated on the ceramic as an electrode by infiltration. It is divided into two types of high-frequency porcelain and low-frequency porcelain. Capacitors with a small positive capacitance temperature coefficient are used in highly stable oscillating circuits as circuit capacitors and pad capacitors. Low-frequency ceramic dielectric capacitors are limited to bypass or DC-blocking in circuits with low operating frequencies, or where stability and loss requirements are not high (including high frequencies).
