A separate specification lists the rated ripple current IAC, R at 100Hz at the upper temperature (+ 85 ℃, + 105 ℃ or + 125 ℃). The known core temperature (the core temperature can also be indirectly calculated by ripple current load, ambient temperature, wind speed and other parameters) and the service life under working voltage depend on the following service life formula:

Central temperature、  Rated life at rated voltage W.V

Central temperature 、 Time voltageThe inferred life of the system
