With increased temperature the dielectric response is quicker, which results in similar behaviour at higher frequency for AC excitation, or shorter time for DC excitation. In other words, the values change, but the general shape of the curves is preserved.

frequency or skin effect. 13.2.1 Frequency Effect The frequency of the AC voltage produces a second effect on the conductor resistance due to the nonuniform distribution of the current. This phenomenon is known as skin effect. As frequency increases, the current tends to go toward the surface of the conductor and the current density decreases

Variations in dielectric constant with temperature in capacitors is the main source of drift for these components. Temperature drift is expressed as a temperature coefficient in ppm/oC or %/temp range. Capacitors The 3 most common types of dielectrics for RF capacitors are: Dielectric type Temp coefficient (TC) Temp range

The insulation may last longer than the rated lifetime if its temperature remains below the rated level for significant periods of time. Figure 4 shows the relationship of insulation life versus temperature normalized at 25°C (100% life).
