The purpose of this utility model is the above-mentioned difficulties that will overcome prior art, for capacitor and connecting of resistor provide a kind of syndeton that does not influence capacitance, and makes its compact conformation, and volume is little, is adapted at using in the small space.
Solution of the present utility model is: make the composite construction of a kind of capacitor and resistor, it is the sheets type ceramic dielectric capacitor of two-sided quilt silver and the single piece that the real core resistive element of chip bonds together by conductive adhesive layer.
The opposite side of above-mentioned ceramic capacitor is by can be by the conductive adhesive layer metal electrode film that bonds on the silver-colored end face.
Above-mentioned conductive adhesive layer can be resin conducting resinl or solder(ing) paste etc.
The side of above-mentioned sheets type ceramic dielectric capacitor can apply insulation and seal material, and is withstand voltage to improve.Sealing material can be epoxy resin, phenolic resins or silicon rubber etc.
The single piece side that capacitor and resistive element are formed preferably is provided with the sheath of being made by polytetrafluoroethylene, polyethylene or nylon etc.
Real core resistive element of above-mentioned chip and metal electrode can be provided with chamfering near capacitor one side, in case glue flows out.
The utility model compared with prior art has following advantage:
1. two-sided by the real core resistance of silver and the composite construction of sheets type ceramic dielectric capacitor, can not have any impact to capacitance.This is the outstanding feature of the present invention.
2. volume is little, and compact conformation is fit to be placed in the small space.
3. under same dielectric thickness condition, the proof voltage of Leaded Ceramic Disc Capacitor and resistance complex, anti-pulse feature and life-span significantly improve.Has extensive use in the electric prospection field.
Description of drawings
Fig. 1 is electric capacity-integrally-built sectional arrangement drawing of resistance complex.
Embodiment
Referring to accompanying drawing, the two sides is bonded as one by the real core resistive element 3 of conductive adhesive layer 2 and carbonaceous by the disk shape ceramic capacitor 1 of silver.Two end faces of wherein real core resistive element 3 are also all had silver layer or other conduction material.The real core resistive element here also claims carbon resistance body or organic real core resistive element.This resistive element is made electric conducting material by carbon black, the mineral powder as filler, and thermosetting resin is made binding agent, and heating and pressurizing is made after mixing.Resistor disc 3 two ends scribble silver layer, constitute electrode.The inventor finds after deliberation, when such resistive element and ceramic capacitor are compounded to form and connect, can the capacitance of capacitor do not had any impact.This is an outstanding effect of the present invention.
More than so-called conductive adhesive layer 2 except comprising various resin conducting resinls, also can be solder(ing) paste etc.Conducting resinl mostly is in epoxy resin and adds silver powder and make, and can also be the conducting resinl of many other types certainly.
