Abstract
The invention discloses a capacitor with a built-in divider resistor. The capacitor comprises a shell, wherein the shell is covered with an end cover; the end cover is provided with two terminals; a capacitor core is arranged in the shell; the capacitor core is electrically connected with the terminals through wires; and the wires between the capacitor core and one terminal or the two terminals are connected with a resistor. The capacitor has the advantages of effectively avoiding breakdown caused by voltage with higher rangeability, greatly prolonging service life, reducing the probability of potential safety hazard, along with simple structure and convenient use.
Description
Technical field
The present invention relates to electron electric power device field, be specially a kind of electric capacity of built-in divider resistance.
Background technology
Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.Electric capacity is to be made of any two insulated from each other and very near conductors of being separated by, and electric capacity is equivalent to open circuit in DC circuit, and in alternating current circuit, circuit passes through between electric capacity by the form of field.Because electric capacity is widely used in the circuit, and the change in voltage amplitude in some circuit is bigger, causes electric capacity breakdown easily, causes potential safety hazard.
Summary of the invention
The electric capacity that the purpose of this invention is to provide a kind of built-in divider resistance is to solve electric capacity of the prior art easily breakdown problem in the bigger circuit of some change in voltage amplitudes.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of electric capacity of built-in divider resistance, include uncovered housing, described housing open-mouth is covered with end cap, two terminals are installed on the described end cap, the electric capacity core body is arranged in the described housing, described electric capacity core body is electrically connected with two terminals on the end cap by lead, it is characterized in that: have access to resistance on the lead between described electric capacity core body and the terminal, have access to resistance respectively on the lead between perhaps described electric capacity core body and two terminals.
The present invention is simple in structure, easy to use, by on the lead between electric capacity core body and the terminal, or and two terminals between lead on have access to resistance and carry out dividing potential drop, can prevent the voltage breakdown electric capacity that amplitude of variation is bigger effectively, improve the useful life of electric capacity greatly, reduced the possibility that potential safety hazard occurs.
Description of drawings
Fig. 1 is a structural representation of the present invention, wherein:
Fig. 1 a is terminal corresponding lead structural representation when inserting resistance, and Fig. 1 b is two terminal corresponding lead structural representations when all inserting resistance.
