Alone stone capacitor is multilayer the another namer of capacitor of pottery and porcelain, english name Monolithic Ceramic Capacitor or MulTI-layer Ceramic Capacitor, abbreviation MLCC, apply extensively at electronic nicety instrument. All sorts of small-sized electron equipment make wave of syntonic, coupling, filter, bypass.

 

 

The basic structure of simple smooth andante capacitor is two electric metal electrode outside be being added by the layer of the medium intermediate of an insulation, basic structure is as follows:

 

Accordingly, multilayer the structure of a capacitor of type pottery and porcelain basically includes 3 much: Medium of pottery and porcelain, the electrode inside the metal, the electrode outside the metal. And multilayer a capacitor of type pottery and porcelain the structure that it is superposition of a many layer, say it is simply by the shunt-wound body of capacitor of many simple smooth andante.

 

 

 

 

Temperament of this kind of capacitor report can be the stablest, basically do not follow the change of temperature, voltage, time, belong to super- stability, kind of stuff of small loss capacitance, applicable asking to stability, dependability circuit of taller high frequency, VHF, VHF is medium.

 

 

Because X7R is a kind of ferroelectric material, can make the capacitor with a larger than NPO medium size consequently. Performance of this kind of capacitor is steadier, along with the change of time of temperature, voltage, its peculiar performance change is not marked, belong to kind of stable capacitance stuff, use in lie between straight, coupling, draw near circuit of wave of road, filter and dependability demand are higher in in high frequency circuit.

 

 

This kind of capacitor has taller dielectric constant, commonly used at producing specific volume bigger, nominal the product of high capacity capacitor with higher capacity. Dan Jirong measures stability relatively X7R is poor, capacity, loss is more sensitive to the test condition such as temperature, voltage, basically use in the electron overall medium oscillation, coupling, filter affects in bypass circuit.

 

Alone stone electric capacity is larger than capacitor of general porcelain interpose (10pF~10μF) , and capacitance big, bulk small, dependability stability of tall, capacitance, high temperature resistant, insulating properties good, cost is low advantage, receive wide application consequently. Alone stone capacitor can replace micaceous capacitor and paper interpose capacitor not only, still replaced certain Tantalum capacitor, wide application is in small-sized and exceed small-sized electron equipment (like liquid crystal watch and miniature instrument) in.

 

 

This is alone the function with stone the basiccest capacitance, advocate if fill discharge process through it,come generation and discharge an electric energy. This basically is the Ⅱ with high capacity kind alone stone capacitance is given priority to, can replace small-sized aluminium to electroanalysis even below certain circumstance capacitance and Tantalum electroanalysis capacitance.

 

 

As a result of alone stone capacitance is not is one guides open system, it is those who pass communication those who have the law change direction and reflect the phenomenon with a two electrified end, accordingly, in circuit it is OK with other component paralell connection, make communication is passed, and dc is cut off to come down, have the effect of bypass.

 

In alternating current road, alone stone capacitance follows to the polarity that inputs signal changes and undertake full discharging, make join thereby alone the circuit of two end behaves stone capacitance guide the position that open, have the effect of coupling.

 

Say commonly, put input end to connect with amplifier or carry alone of stone capacitance for coupling alone stone capacitance; Put with amplifier or carry blast off extremely connect alone stone capacitance is bypass alone stone capacitance.

 

Both all with Ⅱ kind alone stone capacitance is given priority to, especially the capacitance of 0.1uF is in the majority.

 

 

In alternating current road, to signal of compound of a many frequency, we can be used alone stone capacitance parts his partly, generally speaking, we can use a reasonable capacitance alone stone capacitance filters major low frequency signal. This is main with high frequency or ultrahigh frequency alone stone capacitance is given priority to.

 

 

As a result of alone stone capacitance is store can component, accordingly, in circuit, it is OK purify those brief surge pulse signal, the voltage in also can drawing circuit rises and fall the redundant energy that produces erratically. Filter wave basically is given priority to with high frequency product.

 

Brief introduction of capacitance of pottery and porcelain

 

The capacitor pottery and porcelain that capacitance of pottery and porcelain uses tall dielectric constant extruding becomes round canal, wafer or disc to serve as medium, use the law that burn ooze to regard electrode as to be made silver-colored plating on pottery and porcelain. It divides interpose of high frequency porcelain and interpose of low frequency porcelain again two kinds.

 

 

The capacitor pottery and porcelain that uses tall dielectric constant extruding becomes round canal, wafer or disc to serve as medium, use the law that burn ooze to regard electrode as to be made silver-colored plating on pottery and porcelain. It divides interpose of high frequency porcelain and interpose of low frequency porcelain again two kinds. Have small positive electricity to allow the capacitor of temperature coefficient, use in loop of tall stable oscillation, make capacitor as loop capacitor and mat. Be confined to of capacitor of interpose of low frequency porcelain makes bypass in the loop with working inferior frequency or lie between dc to use, or not tall to stability and loss requirement circumstance . This kind of capacitor is unfavorable use in pulse circuit, because of them easily by pulse voltage puncture.

 

 

In the capacitor of high-pressured pottery and porcelain that domain of high-power, high pressure uses, it is good that the requirement has small-sized, tall compression and frequency character wait for a characteristic. As material, electrode and the progress of production technology, the development of capacitor of high-pressured pottery and porcelain has great progress, obtain wide application. Capacitor of high-pressured pottery and porcelain already made one of component with indispensable product of electron of high-power high pressure.

 

The utility of capacitor of high-pressured pottery and porcelain basically distributes the power facilities that is system of power transmission, distribution and the equipment that handle pulse energy.

 

 

 

Alone stone capacitance and ceramics capacitance attribute electric capacity of pottery and porcelain, whole is anatomical look alone the distinction of stone capacitance and ceramics capacitance is: Alone stone capacitance is multilayer the another namer of capacitance of pottery and porcelain, alone stone capacitance is by multilayer medium and many pairs of electrode form, and ceramics capacitor is made by a medium and a pair of electrode commonly, ceramics capacitance cent uprights for high frequency porcelain and low frequency porcelain uprights two kinds.

 

Look on the exterior alone the distinction of stone capacitance and ceramics capacitance is: Alone stone capacitance is the agglomeration after pottery and porcelain sticks a capacitance solder down-lead actually and into, it is quadrate commonly, and ceramics capacitance is a shape, it is wafer appearance mostly; Look on capacity and compression alone the distinction of stone capacitance and ceramics capacitance is: Fall with bulk, alone the capacitance that the capacitance of stone capacitance is more than ceramics capacitance far, and the compression prep above of ceramics capacitance alone the compression of stone capacitance.

 

 

 

1, capacitance is big, stable, capacity limits is 10pF~10uF;

 

2, volume is minor, smaller than CBB capacitance bulk;

 

3, high temperature resistant be able to bear or endure wet sex is good;

 

4, Wen Piao coefficient is small

 

 

1, volume is minor, high frequency character is good;

 

2, than alone stone capacitance compression is tall;

 

3, the size is small, have 0.1uF; only greatly most

 

4, than alone stone capacitance price is low.

 

because alone stone capacitance and ceramics capacitance have different characteristic, the application in the life is endless also and so identical, alone the application of stone capacitance basically is in instrument of camera of liquid crystal watch, electron, miniature, medical treatment instrument, in electronic tuner; And the application of ceramics capacitance basically is to be in loop of high frequency oscillation, bypass, in retreating Ou.
