Dielectric constant of kapton tape
Web19 rows · The dielectric constant k is the relative permittivity of a dielectric material. It is an important parameter in characterizing capacitors. It is unfortunate that the same … WebAt a constant temperature, the dielectric constant decreases as the frequency increases, as shown in Figure 6. Humidity Tests on flat sheets and unencapsulated capacitors showed that the dielectric constant (at 100 Hz and 1 kHz) of Mylar® polyester film increased by 3% as the relative humidity at 23°C (73°F) increased from 20 to 80%.

WebDielectric constants of polyimides, in general, are known to decrease gradually with increasing frequency. For example, Kapton H film (25.4 mm) has a dielectric constant of approximately 3.5 at 1 kHz and 3.3 at 10 MHz [7]. This variation in dielectric constant is attributed to the frequency dependence of the polarization WebMar 1, 2024 · Kapton was selected as extensive research has been carried out using Kapton tape as the dielectric material, therefore it would provide a good baseline result. GRE and PTFE have dielectric constants higher and lower than Kapton, respectively. See Table 1 for dielectric properties of the selected materials.
