How to measure the heat-generation characteristics of a capacitor?

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.

How to determine the temperature rise above ambient of a capacitor?

If the ESR and current are known, the power dissipation and thus, the heat generated in the capacitor can be calculated. From this, plus the thermal resistance of the ca-pacitor and its external connections to a heat sink, it be-comes possible to determine the temperature rise above ambient of the capacitor.

How does heat dissipation affect a capacitor?

1. Capacitor heat generation 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.

How do you determine the allowable power dissipation of a capacitor?

As previously stated, the allow-able power dissipation can be determined by the knowledge of the thermal resistance Θcap, the equivalent series resistance ESR of the capacitor, the maximum allowable internal temperature and the maximum temperature that solder or epoxy on the ter-mination can tolerate without destruction.
