What do dielectric loss and conductance loss mean in capacitor loss?

Dielectric loss refers to the loss caused by the polarization of the dielectric in the capacitor lagging behind the change of the electric field.

As for the conductivity loss, I don't know what loss it refers to.

If you are not engaged in capacitor manufacturing, you rarely consider these parameters when using capacitors.

The energy consumed by a capacitor due to heat during operation is called
capacitor loss. There are dielectric loss and metal loss.

Manufacturers produce capacitors, and the parameter summary stipulates the allowable loss values of these capacitors within a certain frequency range. The loss of capacitors is mainly caused by dielectric loss, conductivity loss and the resistance of all metal parts of the capacitor.
