Description
Technical field
It the utility model is related to a kind of low inductance cylindrical type thin film capacitor.
Background technology
At present, the wiring of cylindrical type thin film capacitor is to be drawn by one end of electrode on the outside of capacitor and be connected to extraction
Terminal, because again in the circuit process of electric current, the counteracting ability of inductance is poor, so this gage system causes the capacitor
Inductance value is bigger, applies in DC filtering circuit occasion, and filter effect and voltage peak absorbing ability are poor, spike electricity
Pressure ratio is larger, easily burns out insulated gate bipolar transistor, and service life is low.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the above, there is provided one kind is simple in construction, peak voltage is small, uses
The low inductance cylindrical type thin film capacitor of long lifespan.
The purpose of this utility model is achieved through the following technical solutions：A kind of low inductance cylindrical type thin film capacitor, bag
Cylindrical type thin film capacitor is included, the upper surface of cylindrical type thin film capacitor is communicated by copper sheet with leading-out terminal, cylindrical type film
Copper rod is provided with capacitor, the tail end of copper rod is communicated by copper sheet with the lower surface of cylindrical type thin film capacitor, the top of copper rod
Communicated by copper sheet with another leading-out terminal.
The utility model has advantages below compared with prior art：
The utility model is passed through with copper rod from cylindrical type intermediate throughholes, and one end is connected to electrode with copper sheet again, and the other end is used
Copper sheet is connected on leading-out terminal, and this mode of connection causes inductance value to decline at least 20%；In the circuit process of electric current, electricity
The counteracting ability of sense is strong, so applies in DC filtering circuit occasion, and filter effect and voltage peak absorbing ability are relatively good,
Peak voltage is smaller, and insulated gate bipolar transistor is played a protective role, service life length.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Label in figure：1- cylindrical types thin film capacitor, 2- copper sheets, 3- leading-out terminals, 4- copper rods, 5- another exit
Son.
Embodiment：
, below will be to the utility model to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Technical scheme in embodiment is clearly and completely described, it is clear that described embodiment is that the utility model part is real
Apply example, rather than whole embodiments.Element and feature described in a kind of embodiment of the present utility model can be with one
The element and feature shown in individual or more other embodiment is combined.It should be noted that for purposes of clarity, in explanation
Eliminate the expression and description of part unrelated with the utility model, known to persons of ordinary skill in the art and processing.It is based on
Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained on the premise of creative work is not paid
There is other embodiment, belong to the scope of the utility model protection.
As Fig. 1 shows a kind of a kind of embodiment of low inductance cylindrical type thin film capacitor of the utility model, including circle
Column type thin film capacitor 1, the upper surface of cylindrical type thin film capacitor 1 are communicated by copper sheet 2 with leading-out terminal 3, cylindrical type film
Copper rod 4 is provided with capacitor 1, the tail end of copper rod 4 is communicated by copper sheet 2 with the lower surface of cylindrical type thin film capacitor 1, copper rod 4
Top communicated by copper sheet 2 with another leading-out terminal 5.
The utility model is passed through with copper rod from cylindrical type intermediate throughholes, and one end is connected to electrode with copper sheet again, and the other end is used
Copper sheet is connected on leading-out terminal, and this mode of connection causes inductance value to decline at least 20%；In the circuit process of electric current, electricity
The counteracting ability of sense is strong, so applies in DC filtering circuit occasion, and filter effect and voltage peak absorbing ability are relatively good,
Peak voltage is smaller, and insulated gate bipolar transistor is played a protective role, service life length.
Finally it should be noted that：Although the utility model and its advantage are described in detail above it should be appreciated that
Various change can be carried out in the case of without departing from the spirit and scope of the present utility model being defined by the claims appended hereto
Become, substitute and convert.Moreover, the scope of the utility model is not limited only to process, equipment, means, method described by specification
With the specific embodiment of step.One of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, root
It can be used according to the utility model and perform the function essentially identical to corresponding embodiment described herein or obtain basic with it
Identical result, existing and to be developed in the future process, equipment, means, method or step.Therefore, appended right
It is required that include such process, equipment, means, method or step in the range of being directed at them.
