Conventional or laminated busbars aid in heat removal through the terminal end. An external heat dissipater, or heat sink, can increase heat removal further, increasing the life of the capacitor. This additional heat sinking can take many forms. The most common heat sink is an aluminum extrusion that attaches to the closed end of the capacitor.
This heating, provoked by the losses of the components that are placed inside, produces an increase of the temperature that should be lower to the maximum working temperatures of the equipment and capacitors.
2. Heat-generation characteristics of capacitors In order to measure the heat-generation characteristics of a capacitor, the capacitor temperature must be measured in the condition with heat dissipation from the surface due to convection and radiation and heat dissipation due to heat transfer via the jig minimized.
Yes, capacitors can be damaged by excessive heat. High temperatures can lead to the degradation of the dielectric material, increased leakage currents, changes in capacitance, internal component damage, and reduced overall performance and lifespan.
Yes, capacitors are sensitive to heat. Excessive heat can affect the performance, reliability, and lifespan of capacitors. High temperatures can lead to changes in capacitance values, increased leakage currents, degradation of dielectric materials, internal component damage, and reduced overall efficiency.
As a point of general reference, it is possible for an electrolytic capacitor to heat up even during normal operation, if the capacitor is exposed to ripple currents. This is a situation where the capacitor is rapidly charged and discharged, either partially or completely. For example, on the output of a rectifier, or in a switching power supply.
