Description
Technical field
The utility model relates to technical field of electronic components, especially a kind of highly inhibited multilayer ceramic capacitor.
Background technology
Multilayer ceramic capacitor (MLCC) is a kind of electronic component using ceramic material, it has such as miniaturization, high capacitance and is easy to the advantages such as installation, be installed on the circuit board of the various electronic products such as such as display unit (such as liquid crystal display, plasma display panel etc.), computer, palmtop PC, mobile phone widely, for charge or discharge.
In the circuit of above-mentioned electronic product, the size of level of noise weighs or affect an important indicator of its service behaviour, and when applying existing multilayer ceramic capacitor, due to (the so-called electrostriction of dielectric electrostriction effect, that is: the strain be directly proportional to field intensity quadratic power that dielectric produces under External Electrical Field) cause capacitor operationally can have an impact to circuit board, make circuit board generation oscillation phenomenon to a certain degree, thus add the level of noise of electronic product, the effect of capacitor and the service behaviour of electronic product are had a strong impact on.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide the highly inhibited multilayer ceramic capacitor that a kind of structure is simple, easy for installation, effectively can suppress the noise produced with electrostriction effect.
To achieve these goals, the utility model adopts following technical scheme:
A kind of highly inhibited multilayer ceramic capacitor, it comprises capacitor body, described capacitor body comprises duplexer and is arranged at the external electrode on the left and right end face of duplexer, it also comprises two symmetrically arranged end runners and an interpolation bolster, the shape of the central longitudinal cross-section of described end runners is horizontal " U " shape, described interpolation bolster be horizontally placed on two end runners between and by two end runners be connected as a single entity;
Two described end runners are welded in lower left and the lower right of capacitor body respectively by the external electrode of correspondence.
Preferably, described end runners comprises welding base, conduction covering and contact pad, described welding base comprises the first horizontal portion be welded on external electrode, the second horizontal portion being parallel to the first horizontal portion, the longitudinal part that is connected as a single entity between the first horizontal portion and the side in the second horizontal portion and by both, on described interpolation bolster, the position that is positioned at longitudinal part is provided with longitudinal hole, described longitudinal part is positioned at longitudinal hole, described conduction covering is coated on interpolation bolster, and described contact pad is arranged on the bottom surface in the second horizontal portion.
Preferably, described welding base is shaping by tin ash colloidal sol.
Owing to have employed such scheme, the utility model can utilize end runners to be welded on circuit board by capacitor body, under the effect of external electric field, can electrostriction phenomena be there is in duplexer, consequent stress can be directly delivered on end runners, instead of acts on circuit board, effectively reduces the crooked radian of circuit board thus, and reduce the vibration amplitude of circuit board, thus achieve the effect suppressing noise; The generation that its structure is simple, easy for installation, effectively can suppress noise, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the highly inhibited multilayer ceramic capacitor of the present embodiment, it comprises capacitor body, the external electrode 2 that capacitor body comprises duplexer 1 and is arranged on the left and right end face of duplexer 1, it also comprises two symmetrically arranged end runners and an interpolation bolster 3, the shape of central longitudinal cross-section of end runners be horizontal " U " shape, and interpolation bolster 3 to be horizontally placed between two end runners and to hold runners to be connected as a single entity by two; Two end runners are then welded in lower left and the lower right of capacitor body respectively by the external electrode 2 of correspondence.So, end runners can be utilized to be welded on circuit board by capacitor body, under the effect of external electric field, can electrostriction phenomena be there is in duplexer 1, consequent stress can be directly delivered on end runners, instead of acts on circuit board, effectively reduces the crooked radian of circuit board thus, and reduce the vibration amplitude of circuit board, thus achieve the effect suppressing noise.
For ensureing the functional effect of end runners, the end runners of the present embodiment comprises welding base, conduction covering 4 and contact pad 5; Wherein, welding base comprises the first horizontal portion 6 be welded on external electrode 2, is parallel to the second horizontal portion 7 in the first horizontal portion 6, between the first horizontal portion 6 and the side in the second horizontal portion 7 and the longitudinal part 8 both be connected as a single entity, on interpolation bolster 3, the position that is positioned at longitudinal part 8 is provided with longitudinal hole, longitudinal part 8 is positioned at longitudinal hole, conduction covering 4 is coated on interpolation bolster 3, and contact pad 5 is arranged on the bottom surface in the second horizontal portion 7.So, contact pad 5 can be utilized by capacitor welding on circuit board, utilize the version of welding base and the structural relation with interpolation bolster 3, good buffering effect can be realized.
For simplifying the structure of whole end runners, be convenient to carry out production assembling to it, the welding base of the present embodiment is shaping by tin ash colloidal sol.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
