[utility model content]
Technical problem to be solved in the utility model is: make up above-mentioned the deficiencies in the prior art, propose a kind of laminated sheet type electronic component, the lifting that improves of its performance under high frequency environment.
Technical problem of the present utility model is solved by following technical scheme:
A laminated sheet type electronic component, comprises that laminated body and the pair of end electrode of cuboid, described pair of end electrode are separately positioned on the two ends on a side of described laminated body, and extends to separately on the end face of described laminated body; Described side is the side parallel with described laminated body stack direction.
The beneficial effect that the utility model is compared with the prior art is:
Laminated sheet type electronic component of the present utility model, the termination electrode of one end is only arranged on a side of laminated body and on end face, the situation that covers two end faces and four sides with respect to termination electrode in the laminated sheet type electronic component of prior art, the size of termination electrode significantly reduces.Simultaneously, the side arranging is the side parallel with laminated body stack direction, termination electrode and interior electrode retaining collar are vertically opposite settings around plane, and be no longer parallel vis-a-vis setting, the relative area of termination electrode and interior electrode is less, therefore the parasitic capacitance that termination electrode produces the interior electrode of laminated body significantly reduces, the lifting that improves of the performance of electronic devices and components under high frequency.
[accompanying drawing explanation]
Fig. 1 is the structural representation of laminated sheet type electronic component in prior art;
Fig. 2 is the structural representation of a kind of improved laminated sheet type electronic component in prior art;
Fig. 3 is the structural representation of the laminated sheet type electronic component of the utility model embodiment.
[embodiment]
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further details.
As shown in Figure 3, be the structural representation of the laminated sheet type electronic component of this embodiment.Laminated sheet type electronic component comprises laminated body 1 and the pair of end electrode 3 of cuboid.The material of termination electrode 3 is electrocondution slurry.Pair of end electrode 3 is separately positioned on the two ends on a side of laminated body 1, and extends to separately on the end face of laminated body 1, and the described side of setting is the side parallel with laminated body 1 stack direction (direction as shown by arrows in FIG.).Shown in figure, for being arranged on the two ends of side A, and extend to end face from each end.
When welding is installed, laminated sheet type electronic component is provided with the side (being side A in Fig. 3) of termination electrode as basal surface, with pcb board Surface Contact, the electrode part at basal surface two ends is welded on pcb board by tin cream, electrode part on end face is climbed along electrode surface for the tin cream of welding, guarantees the reliability of welding.Preferably, can on the side of laminated body, identification element be set, the direction of installing as laminated body.Further preferably, on adjacent two sides (in figure, lower surface is not shown) of the side A with being provided with termination electrode, be provided with identification element 4.Product placement direction while making formation termination electrode is the placement direction of laminated sheet type electronic component shown in figure also, therefore on two adjacent sides, arranges, and can be convenient to technological operation.Like this, during welded and installed, can identify the directivity of laminated sheet type electronic components by identification element 4, and then guarantee correctly installing and using of components and parts.During installation, using the surface at identification element 4 places as sidepiece, side A is down as bottom, electrode can with pcb board welded and installed, guarantee correct installation.
Preferably, termination electrode is positioned at the part on side, accounts for along its length 1/8～1/4 of laminated body 1 long limit.Also the width p that is the electrode part on the A of side shown in Fig. 3 is 1/8～1/4 of the long limit L of laminated body.Electrode part divides and is arranged in this length range, both can guarantee to have enough electrodes to weld for reliability, is unlikely to again to form on side the waste that wider electrode causes electrode material.Similarly, the area that termination electrode is positioned at the part on end face accounts for 40%～50% of laminated body 1 face area, and existing enough parts are climbed for tin cream, are unlikely to again to cause waste.
The laminated sheet type electronic component of this embodiment only arranges termination electrode on side and end face, and the size of termination electrode has significantly and reduces with respect to the size of the termination electrode in the components and parts of prior art.Simultaneously, the side arranging is the side parallel with laminated body stack direction, termination electrode and interior electrode retaining collar are vertically opposite settings around plane, and be no longer parallel vis-a-vis setting, the relative area of termination electrode and interior electrode is less, therefore the parasitic capacitance interior electrode of laminated body 1 being produced also can significantly reduce, the lifting thereby the performance of electronic devices and components under high frequency is further improved.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, make without departing from the concept of the premise utility some substituting or obvious modification, and performance or purposes identical, all should be considered as belonging to protection range of the present utility model.
