Wide temperature range. At temperatures above 20 C the temperature coefficient of capacitance for OS-CON capacitors is comparable to aluminum and tantalum electrolytic capacitors. Also, the change is roughly linear and increases with temperature. The ESR of OS-CON capacitors change little with temperature. In this respect OS-CON capacitors are as good or better than good ceramic capacitors.
Manufactures often specify the impedance ratio at two temperatures.
From the datasheets it is known that at 20 C and 100 kHz, the ESR is 60 m W , and that the impedance at 100 C is 0.9 times the impedance at 20 C. Solution . Click here for more detail . Electrolytes deteriorate over time, a process that is enhanced at elevated temperatures. However, some of the claims with regard to the superior longevity of OS-CON capacitors may be overstated. For example, the lifetime of an aluminum electrolytic capacitor tends to be inversely proportional to the physical dimensions.
