Class 2 dielectrics

WebFeb 28, 2024 · Class 1 dielectrics are extremely stable over voltage and temperature and display very little aging. By far the most common type of capacitor using Class 1 dielectrics is C0G (also known as NPO). Given equal capacitance values, these capacitors are much larger in size than those that use class 2 dielectrics because the relative permittivity of ... WebThis phenomenon for ceramic class 2 and plastic film dielectrics is related to dielectric relaxation in which the time constant of the electrical dipoles is the reason for the frequency dependence of permittivity. The graphs below show typical frequency behavior of the capacitance for ceramic and film capacitors.
