Shown on this slide is a comparison of the ECAS series short circuit failure mode to tantalum type capacitors. Unlike the traditional manganese dioxide tantalum type capacitors, the ECAS series has a benign failure mode for short circuit failure. The ECAS series will not burn or explode. For combustion to occur three things are required: a heat source, oxygen, and fuel. In both cases shown, the current flow through the short circuit failure in the capacitor dielectric material (such as aluminum oxide or tantalum pentoxide) provides the heat source. The manganese dioxide tantalum type will release oxygen at high temperatures, the conductive polymer of the ECAS series polymer aluminum capacitors do not contain, nor will it release any oxygen. For the third element, fuel, it is necessary to compare the ignition points of tantalum and aluminum. With aluminum’s higher flash point (about 400°C) and activation energy, the ECAS series is more difficult to burn than tantalum capacitors. The ECAS series also has the built in safety feature reviewed previously – the current block function and self-repairing ability - that aids to limit combustion of the capacitor in case of a short circuit failure.
