Dielectric Loss Tangent

Dielectric Loss Tangent measures how much energy from an electric field within a material is converted into heat. When an alternating electric field is applied to a dielectric (insulating) material, some energy is stored, and some is lost as heat due to the material's internal properties. The Loss Tangent is a ratio that compares the energy lost to the energy stored, indicating the efficiency of the material in electrical applications. A low Loss Tangent signifies the material is efficient with minimal energy loss, which is important in circuits, capacitors, and high-frequency systems.
