Description
technical field [0001] The invention relates to the field of electronic power devices, in particular to a 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 need to be connected to the circuit for use. Since the capacitor generally contains impregnating liquid, if the installation posture of the capacitor is incorrect, the impregnating liquid will easily overflow, which will easily affect the performance of the capacitor and the connected circuit, and the capacitor is generally...
