Product Details
As there is a maximum temperature to which the wire can rise during an overload, if the resistor is already dissipating heat, then the pulse energy applied should be less than that allowed by the graph. Using the formula below we can estimate the equivalent energy of a pulse applied to a resistor that is already dissipating power.It should also be noted that for repetitive pulses the average power dissipated must not exceed the continuous power rating of the resistor.
