Capacitor Specifications: what they mean

Consider Operating Temperature in Selecting Capacitors. Environment factors are also needed to consider on how to select capacitors. If your product will be exposed to an environment temperature of 100''C, then do not use a capacitor that is only rated at 85''C. Likewise, if the minimum environment temperature is -30''C, then do not …
