            Monolithic capacitor is called a multilayer ceramic capacitor, ceramic capacitor or multi-layer English name monolithic ceramic capacitor, referred to as MLCC


            Structure

            The basic structure of a simple parallel plate capacitor is composed of an insulating medium layer and two conductive metal electrodes:

            Therefore, the structure of multilayer chip ceramic capacitors mainly includes three parts: ceramic dielectric, metal inner electrode, and metal electrode. The multilayer chip ceramic capacitor is a multilayer laminated structure, which is simply composed of a plurality of simple parallel plate capacitors.


            Classification
            A class
            Temperature compensated NPO dielectric
            This capacitor is the most stable, do not vary with temperature, voltage, time change basically, low loss of capacitance material type is super stable and suitable for stability, higher reliability of HF, UHF, VHF circuit.
            Two
            X7R dielectrics with high dielectric constant
            Because X7R is a ferroelectric capacitor, which can produce a larger capacity than NPO medium. The performance of the capacitor is stable with temperature, voltage, time change, its unique properties not changed significantly, is a stable capacitance material type, used in DC blocking, coupling, near the road, in the high frequency circuit filter circuit and high reliability requirements in.
            three classes of initials
            Semiconductor Y5V dielectrics
            The dielectric constant of the capacitor is high, large capacity capacitor products used in the production of large volume, high nominal capacity. However, its capacity stability is worse than that of X7R, and its capacity and loss are more sensitive to temperature, voltage and other test conditions.
            Monolithic capacitor than ordinary ceramic capacitor large (10pF~10 F), and electric capacity, small volume, high reliability, stable capacitance, high temperature resistance, good insulation, low cost, wide application. Monolithic capacitor can not only replace the mica capacitor and capacitor, also replace some tantalum capacitors, widely used in small and ultra small electronic devices (such as LCD watches and micro instruments).


            Characteristic and function
            Characteristic
            Good temperature characteristics, good frequency characteristics. With the increase in the frequency of the general capacitance, the capacitance showed a decline in the law, the decline in the capacity of single stone is relatively small, relatively stable capacity.

            Effect
            1, energy storage exchange
            This is the most basic function of the single capacitor, mainly through its charging and discharging process to produce and cast a power. This is mainly based on the large capacity of class II monolithic capacitors, in some cases can even replace the small aluminum electrolytic capacitors and tantalum electrolytic capacitors.
            2, through the bypass (bypass and coupling)
            Because the monolithic capacitor is not a conduction body, it is through the exchange of steering and reflect the electrically charged phenomenon, therefore, in a circuit it can with other parallel components, the AC and DC is through the barrier down, to bypass the role.
            In the alternating current circuit, the monolithic capacitor can be charged and discharged according to the polarity change of the input signal, so that the circuit at the two ends of the monolithic capacitor can be connected with a conducting state, and the coupling effect can be realized.
            Generally speaking, and amplifier or op amp input connected monolithic capacitors for coupling monolithic capacitors; and monolithic capacitor amplifier or op amp emitter connected to bypass monolithic capacitor.
            Both of them are dominated by class II monolithic capacitors, especially those of 0.1uF.
            3, frequency discrimination filter
            In AC circuits, the signal for a multi frequency mixing, we can use the monolithic capacitors separate, monolithic capacitors in general, we can use a reasonable amount of capacitance will filter out most of the low frequency signal. This is mainly based on high-frequency or ultra high frequency monolithic capacitor.
            4, surge voltage suppression
            Because the monolithic capacitor is an energy storage element, therefore, in the circuit, it can remove those transient surge pulse signal can also absorb circuit voltage fluctuations generated by the excess energy. The filter is mainly based on high frequency products.


            Application status
            Application scope:
            Widely used in electronic precision instruments. A variety of small electronic equipment for resonance, coupling, filtering, bypass.
            Capacity range:
            10pF~10 F
            Withstand voltage:
            Two times rated voltage.
            In addition to general characteristics of monolithic capacitor capacitor "vibration through", it also has the advantages of small volume, large volume, long life, high reliability, suitable for surface mounting. With the rapid development of the electronics industry in the world, as the basic components of the electronics industry, monolithic capacitors are also developing at an alarming rate, increasing by 10[%] to 15[%] per year. Demand for the world's monolithic capacitors in more than 200 billion, 70[%] from Japan, followed by Europe and the United States and Southeast Asia (including China). With the improvement of the reliability and integration of chip products, the use of the product is more and more widely. Such as computers, telephones, program-controlled switches, sophisticated testing equipment, radar communications, etc..
