Abstract
The utility model discloses a high-capacity ceramic capacitor which is formed by connecting at least two ceramic capacitor chips in parallel via two metal outlet frames; two outer electrodes of each ceramic capacitor chip are respectively and fixedly connected to the two metal outlet frames; and both the metal outlet frames have mounting ends. Compared with the prior art, the high-capacity ceramic capacitor is formed by connecting the at least two ceramic capacitor chips in parallel via the two metal outlet frames, so that the capacitance of the ceramic capacitor is greatly increased, the highly difficult design of ultralow ESR and ultralow ESL is realized and a better filtering effect is achieved.
Description
Technical field
The utility model relates to a kind of ceramic capacitor.
Background technology
Chip ceramic capacitor is except that the general character characteristics that have capacitor " to hand over every straight-through ", and it also has, and volume is little, specific volume is big, the life-span is long, reliability is high, be fit to characteristics such as mounted on surface.Along with the develop rapidly of world's electron trade, as the base components of electron trade, chip capacitor also advances with surprising rapidity, and is annual with 10%～15% speed increase.At present, the demand of world's sheet capacitor is more than 2,000 hundred million, and 70% comes from Japan, secondly is American-European and Southeast Asia (containing China).Along with sheet holds the raising of product reliability and integrated level, the scope of its use is more and more wider, is widely used in various military-civil complete electronic sets and electronic equipment, as computer, phone, stored-program control exchange, accurate tester, radar communication etc.
But because the restriction of multiple-layer sheet ceramic capacitor manufacturing process, the thickness of product, inner electrode layer number are all restricted, its finite capacity under the certain situation of size.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of big capacity ceramic capacitor is provided.
The utility model adopts following technical scheme:
A kind of big capacity ceramic capacitor, it is drawn frame by at least two ceramic chip capacitors by two metals and is connected in parallel and forms, two external electrodes of every ceramic chip capacitor are fixedly connected on these two metals respectively and draw on the frame, and these two metals are drawn frame and all had installation end.
Described at least two ceramic chip capacitor Horizontal Tiles are provided with.
Include at least four ceramic chip capacitors, this at least four ceramic chip capacitor Horizontal Tiles and stacked in multi-layers setting, described two metals are drawn frame and are had the structure that adapts with the ceramic chip capacitor set-up mode.
By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of big capacity ceramic capacitor of the present utility model is owing to draw frame by at least two ceramic chip capacitors by two metals and be connected in parallel and form, thereby increased the capacitance of ceramic capacitor greatly, realize the highly difficult design of ultralow ESR, ultralow ESL, reached better filter effect.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment one;
Fig. 2 is the perspective view of the utility model embodiment two.
Embodiment
Below the utility model will be further described by embodiment.
Embodiment one
With reference to Fig. 1, a kind of big capacity ceramic capacitor of the present utility model, drawing frame 21,22 by four ceramic chip capacitors 10 by two metals is connected in parallel and forms, four ceramic chip capacitor 10 Horizontal Tile settings, their external electrode is welded to connect respectively at two metals and draws on the frame 21,22, makes big capacity ceramic capacitor compact overall structure, reliable and stable.
After having adopted the structure of this embodiment, if the capacity of a ceramic chip capacitor 10 is the X microfarad, then the capacity of a kind of big capacity ceramic capacitor of this embodiment is the 4X microfarad, has increased the capacitance of ceramic capacitor greatly.
Embodiment two
With reference to Fig. 2, a kind of big capacity ceramic capacitor of the present utility model, drawing frame 21,22 by 12 ceramic chip capacitors 10 by two metals is connected in parallel and forms, six triplex rows, two row in these 12 ceramic chip capacitors 10 are provided with, other six same triplex row two row are provided with, be stacked as two-layer then, two external electrodes separately of these 12 ceramic chip capacitors 10 are welded to connect respectively at two metals draws on the frame 21,22, makes big capacity ceramic capacitor compact overall structure, reliable and stable.
After having adopted the structure of this embodiment, if the capacity of a ceramic chip capacitor 10 is the X microfarad, then the capacity of a kind of big capacity ceramic capacitor of this embodiment is the 12X microfarad, has increased the capacitance of ceramic capacitor greatly.
Above-mentioned only is two embodiments of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
