The maximum power dissipation by case size can be determined using the below left table. The maximum power dissipation rating stated in the table must be reduced with increasing environmental operating temperatures. Refer to the below right table for temperature compensation requirements. Case Code Maximum Power Dissipation (P max) mWatts at 25°C with +60°C Rise KEMET MIL–PRF–39006/22/ 25/30/31 Case Size B T2 715 Temperature Compensation Multipliers for Maximum Power Dissipation (P max) T≤45°C 45°C<T≤85°C 85°C<T≤125°C 1.00 0.50 0.10 T= Environmental Temperature Using the P max of the device, the maximum allowable rms ripple current or voltage may be determined. I(max) = √Pmax/R E(max) = Z √Pmax/R I = rms ripple current (amperes) E = rms ripple voltage (volts) P max = maximum power dissipation (watts) R = ESR at specified frequency (ohms) Z = Impedance at specified frequency (ohms) The maximum power dissipation rating must be reduced with increasing environmental operating temperatures.
