WebMar 11, 2024 · Last Modified Date: March 11, 2024. Dissipation factor is a measurement of how inefficient the insulating material of a capacitor is. It typically measures the heat that is lost when an insulator such as a dielectric is exposed to an alternating field of electricity. A capacitor generally has two metal plates and some kind of insulator in between. WebThe ceramic capacitor shows similar trend in its dissipation factor with temperature as that of the teflon capacitor only at high frequencies, as shown in Figure 4. That is, a steady but very slight increase in the dissipation factor is associat- ed with increase in temperature at frequencies at and above 20 kHz.
