A lossy dielectric is a material that not only stores electrical energy in the form of an electric field when subjected to an electric field, but also dissipates some of that energy as heat due to its resistive properties. This energy loss is typically characterized by the material's loss tangent, which indicates the ratio of the resistive (real) power loss to the reactive (imaginary) power stored. Lossy dielectrics are commonly used in applications such as capacitors and RF components, where energy dissipation is a critical factor in performance. Examples include certain plastics and ceramics that may exhibit significant dielectric losses at specific frequencies.

What happens when dielectric breakdown occurs?
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
