Abstract
The utility model relates to a ceramic capacitor, in particular to a ceramic capacitor with multiple core assemblies, which comprises at least three ceramic capacitor cores connected in parallel and then connected in series. Compared with the prior art, by adopting the structural design of the ceramic capacitor with the multiple core assemblies, the breakdown voltage resistance of equivalent capacitance is greatly improved with capacity and equivalent resistance both unchanged.
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.
Two indexs are arranged in the specification of capacitor, the one, its capacitance, the one, its voltage endurance capability.When using capacitor, the added voltage of two-plate must be less than or equal to its withstand voltage, otherwise capacitor can be breakdown.Also there is such problem in chip ceramic capacitor.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of breakdown voltage resistant higher multicore group ceramic capacitor is provided.
The utility model adopts following technical scheme:
A kind of multicore group ceramic capacitor, it is composed in series after by the parallel connection of at least three ceramic chip capacitors elder generation.
Described at least three ceramic chip capacitors are drawn frame by at least three metals and are linked together.
Described at least three ceramic chip capacitors are welded on described at least three metals and draw on the frame.
Described at least three metals are drawn frame and are respectively first and draw frame, second and draw frame and be connected with at least one and draw frame, and this first is drawn frame and second and draw and all have installation end on the frame.
Described ceramic chip capacitor adopts the Horizontal Tile mode when parallel connection.
By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of multicore group ceramic capacitor structural design of the present utility model has realized improving the breakdown voltage resistant of equivalent capacity greatly under the situation that does not change capacity and equivalent resistance.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment;
Fig. 2 is the plan structure schematic diagram of the utility model embodiment.
Embodiment
Below the utility model will be further described by embodiment.
See figures.1.and.2, a kind of multicore group ceramic capacitor of the present utility model, by four ceramic chip capacitors 11,12,13,14 draw frame 21 by first, second draws frame 22, connect to draw and be composed in series after the frame 23 first parallel connections, wherein ceramic chip capacitor 11,12 draw frame 21 by first draws frame 23 and is connected in parallel with being connected, ceramic chip capacitor 13,14 draw frame 22 by second draws frame 23 and is connected in parallel with being connected, and then with ceramic chip capacitor 11,12 chipsets that compose in parallel and ceramic chip capacitor 13,14 chipsets that compose in parallel are connected, and at last the installation end 221 of drawing frame 22 by first installation end 211 and second of drawing frame 21 is drawn.
Above-mentioned only is an embodiment 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.
