The tantalum metal has a dielectric constant of approximately 27. The price for solid tantalums is relatively high due to mainly the high cost of the tantalum powder. The solid electrolyte theoretically has no limitations in operation and storage time.

Recommendation for voltage derating means that the actual capacitor shall be used in the application at a lower voltage than the rated voltage. Derating is expressed usually by percentage of rated voltage that shall be subtracted. For example, 20% derating means that the capacitor shall be used at 80% of rated voltage at the specific applications (10V capacitor to be used on 8V maximum).

PULSE LOADS In many applications, the resistor will be subjected to pulse loads. We make distinctions between periodical/repetitive loads and pulse trains; on one hand, where the pulse is repeated at a certain frequency, and on the other separate pulses where a possible repetition will occur after so long time that the resistor has recovered its original ambient temperature.
