As electronic devices become smaller and lighter in weight, the component mounting density increases, with the result that heat dissipation performance decreases, causing the device temperature to rise easily. In particular, heat generation from the power output circuit elements greatly affects the temperature rise of devices.

In summary, the properties of capacitors and temperature are tightly coupled, and the heat generation mechanisms of several types of SCs are radically not identical; thus, it is imperative to be aware of the thermal characteristics of capacitors. The next section will explore the heat generation mechanisms of each component in more detail. 3.2.
In higher power cases, the larger heat load may require additional cooling by means of an external heat dissipator or heat sink (not unknown, but not common with capacitors since they take up a lot of space); a fan, which can forcefully direct cooling air over the capacitor; or liquid cooling.
A thermal capacitor is a device capable of mitigating temperature rise or fluctuations by absorbing and releasing thermal energy. It is needed to optimize thermal designs for an average heat load instead of a peak condition ( Figure 1a ). In this article, a thermal capacitor refers to this function.
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.
Cooling a capacitor helps to enhance its performance as well as its reliability. Cooling will extend its life; taking away more heat from the capacitor can also give it more power-carrying ability.
