Abstract
The utility model discloses a low-loss high-ripple capacitor. The size of the capacitor is 10mm*20mm. The capacitor comprises an aluminium housing, positive-pole aluminium foil, negative-pole aluminium foil, and electrolytic paper, wherein the positive-pole aluminium foil, the negative-pole aluminium foil and the electrolytic paper are all disposed inside the aluminium housing. An opening of the aluminium housing is provided with a skin head. A positive wire is riveted on the positive-pole aluminium foil, and a negative wire is riveted on the negative-pole aluminium foil. The negative wire is additionally covered by a layer of foil. The width of the positive-pole aluminium foil is 10mm, and the width of the negative-pole aluminium foil is 13mm, and the width of the electrolytic paper is 15mm. The width of the layer of foil is less than the width of the negative-pole aluminium foil by 0.5mm-4.2mm. In the utility model, the width of the aluminium foil of the aluminium electrolytic capacitor is adjusted and reduced, the length of the aluminium foil is prolonged to some extent, the number of winding circles is increased, and a capability of resistance to a ripple current of a product is improved.
Description
Technical field
The utility model belongs to electrolytic capacitor and manufactures field, is specifically related to a kind of low-loss, high ripple capacitor.
Background technology
Loss is the important indicator of capacitor, becomes the geometric ratio relation with capacitor life-span, and loss is large, capacitor life-span is just shorter, and capacitor is easily heating just, bears ripple current just little, therefore be necessary to reduce the loss of capacitor product, improve anti-ripple current ability, increase life of product.In the electricity-saving lamp application, capacitor is as important electronic devices and components; Wherein the lead capacitance of size 10 * 20 (mm) is comparatively commonly used.
Summary of the invention
The purpose of this utility model is to provide a kind of low-loss, high ripple capacitor, and it is reasonable in design, has reduced to a certain extent the product loss, the product longer service life.
The technical solution of the utility model is: a kind of low-loss, high ripple capacitor, it is of a size of 10 * 20 (mm), comprise aluminum hull, and be arranged at the positive pole aluminium foil in aluminum hull, negative pole aluminium foil and electrolytic paper, described positive pole aluminium foil, electrolytic paper, the negative pole aluminium foil, electrolytic paper overlapping coiling impregnation electrolyte, the aluminum hull opening part is provided with leather point, on positive pole aluminium foil, riveted joint has positive wire, on the negative pole aluminium foil, riveted joint has negative wire, described negative wire place adds the lid layer foliation, it is characterized in that: the wide 10mm of paper tinsel of described positive level aluminium foil, the wide 13mm of the paper tinsel of negative pole aluminium foil, the wide 15mm of the paper of electrolytic paper, the wide width of the paper tinsel than negative pole aluminium foil of the paper tinsel of described foliation 0.5-4.2mm.
As preferably, the paper tinsel of foliation is wide is 9mm.
Above-mentioned size 10 * 20 (mm), be diameter 10mm, height 20mm.
Beneficial effect: the utility model provides the low-loss that is of a size of 10 * 20 (mm), high ripple capacitor, is applicable to whole voltage.The utility model, by the adjustment to aluminium electrolytic capacitor aluminium foil width, reduces sheet wide, the length that has extended to a certain extent aluminium foil, the coiling number of turns of increase core bag, the anti-ripple current ability of improving product.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Fig. 2 is negative pole aluminium foil foliation schematic diagram.
In figure 1, aluminum hull, 21, positive wire, 22, negative wire, 3, leather point, 4, positive pole aluminium foil, 5, the negative pole aluminium foil, 6, electrolytic paper, 7, foliation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of low-loss, high ripple capacitor, it is of a size of 10 * 20 (mm), comprise aluminum hull 1, and be arranged at the positive pole aluminium foil 4 in aluminum hull 1, negative pole aluminium foil 5 and electrolytic paper 6, described positive pole aluminium foil 4, electrolytic paper 6, negative pole aluminium foil 5, electrolytic paper 6 overlapping coiling impregnation electrolyte, aluminum hull 1 opening part is provided with leather point 3, on positive pole aluminium foil 4, riveted joint has positive wire 21, on negative pole aluminium foil 5, riveted joint has negative wire 22, described negative wire 22 places add lid layer foliation 7, the wide 10mm of paper tinsel of described positive level aluminium foil, the wide 13mm of the paper tinsel of negative pole aluminium foil, the wide 15mm of the paper of electrolytic paper, the wide width of the paper tinsel than negative pole aluminium foil of the paper tinsel of described foliation 0.5-4.2mm.
As preferably, the paper tinsel of foliation is wide is 9mm.
