Abstract

The invention discloses a grounded capacitor which can radiate and position. The capacitor comprises a shell, wherein the shell is covered by an end cover; two terminals are arranged on the end cover; a capacitor chip is arranged in the shell; a grounded wire is connected to a lead between the capacitor chip and one terminal; a button switch is connected to the grounded wire; the outer wall of the shell is connected to a radiating fin; a positioning ring is mounted on the bottom of the shell; and the bottom center of the positioning ring is provided with a positioning hole or a positioning core column.

Description

technical field [0001] The invention relates to the field of electronic power devices, in particular to a grounding capacitor capable of dissipating heat and positioning. Background technique [0002] Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. Capacitance is composed of any two conductors that are insulated from each other and are very close to each other. In a DC circuit, a capacitor is equivalent to an open circuit. In an AC circuit, a circuit passes between capacitors in the form of a field. Capacitors are used in access circuits, especially in some circuits that introduce alternating current from the power grid. Because the alternating current in the power grid sometimes has a surge voltage and generates too high voltage, the electricity in the connected circuit is easily broken down. Capacitors in the art do ...
