The dielectric constant is an electrical parameter measured to understand the insulating properties of materials. It is a crucial property included in the specification of any capacitor used to prepare electronic gadgets. We at Infinita Lab are committed to providing the best routine and advanced Dielectric Constant Testing for our clients in the USA and worldwide. Our testing laboratory has various state-of-the-art instruments and methodologies to perform the required tests.
Dielectric Constant Testing
The dielectric constant is an electrical parameter measured to understand the insulating properties of materials. It is the ratio of capacitance induced between two metallic plates with the insulator between the plates to the capacitance with air or vacuum. The dielectric constant is a crucial property in the specification of any capacitor. Dielectric testing is also one of the measurement metrics for characterizing polymeric materials, ceramics, solvents, biomaterials in aqueous media.
Dissipation factor and loss tangent, which are used in lower and higher frequency applications, respectively, are other parameters measured along with dielectric constant to evaluate an insulator’s efficiency. Dielectric testing measurements are typically performed in testing labs at room temperature to 500 °C, and 10Hz to 10Mhz frequencies depending on the testing standard followed (ASTM) and the application for which the material is tested in the laboratory.
