Perhaps I had not phrased my question correctly, however, found the answer here under capacitor working temperatures:
"Working temperature: All capacitors have a limited working temperature range whether ceramic capacitors, electrolytic capacitors, tantalum capacitors or whatever type. This specification details the limits within which the capacitor will work satisfactorily and over which it is designed to operate.
Some aspects that limit the working range of a capacitor are the voltage - this falls with increasing temperature; the ripple current - again lower with increasing temperature. The lower temperature specification can be governed by a number of factors. One is the electrolyte operation in components such as electrolytic capacitors. The working temperature is particularly important for electrolytic capacitors as their expected life falls rapidly with increasing temperature.
Temperature coefficient: Capacitors, like all components vary with temperature. The degree is relatively small, and does not make a difference in circuits where the value is not critical, but in others where the circuit is dependent upon the exact value, e.g. an LC oscillator, etc, the temperature coefficient can be very important.
The temperature coefficient is often expressed as the variation in parts per million per degree Celsius."
