* If any doubt arises, measure the current after applying voltage (voltage treatment) for 30 minutes at + 105 C. The rated voltage should be
applied for 6.3 to 16.3 WV, while temperature reduction voltage should be applied for 25 WV.
** To use a Vishay OS-CON capacitor when the operating temperature exceeds + 85 C on a component with a rated voltage of 25 V, reduce
the voltage by 0.25 V for every degree (1 C) relative to the value at + 85 C (25 V).
