Heat dissipation distance of low voltage capacitor

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 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. .
