Description

Technical Field

[0001] The utility model relates to the field of electronic components, in particular to a high heat dissipation type electrolytic capacitor. Background Art

[0002] Electrolytic capacitors are capacitors that use electrolytes as cathode materials. They play a key role in many electronic fields with their high capacitance and excellent energy storage capacity. In electrolytic capacitors, "electrolytic" refers to the characteristic that the cathode material is an electrolyte, while "capacitance" refers to the ability of this component to store charge. During the operation of electrolytic capacitors, heat energy is inevitably generated due to the resistance generated by the current passing through the internal electrolyte. This heat energy is usually manifested as an increase in the temperature of the capacitor. If the temperature is too high, it may cause damage to the circuit board and pose certain safety risks. For this reason, we have proposed a high heat dissipation electrolytic capacitor. Utility Model Content
