Capacitor in Electronics – What It Is and What It Does

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

6 FAQs about [What does capacitor heat dissipation mean ]

What determines the heat dissipation capability of a capacitor?

The heat dissipation capability of the capacitor is determined by the thermal characteristics of the capacitor surface and the thermal conductivity of the capacitor’s medium that separates it from its surroundings. The heat withstanding capacity of the leads, lugs, and terminals also affects the heat dissipation capability of the capacitor.

What is a dissipation factor in a capacitor?

The dissipation factor, also known as the loss tangent, measures the amount of energy lost as heat in a capacitor. It represents the ratio of the capacitor’s equivalent series resistance (ESR) to its capacitive reactance.

How does a heat dissipater work on a capacitor?

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.

What determines the heat dissipation capability of an inductor?

The heat dissipation capability of an inductor is directly related to its surface area. The heat dissipation capability of a capacitor is determined by the thermal characteristics of the capacitor surface and the thermal conductivity of the capacitor’s medium that separates it from its surroundings.

How do I reduce the dissipation factor of a capacitor?

To minimize the dissipation factor in your circuit you may need to choose a capacitor with a higher Q factor and reduce the resistance in the circuit. Some things you can do to reduce this resistance is increased quality of the pads and conductors. Clean solder joints will also help with the resistance.

Does a capacitor need a heat dissipator?

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.
