Single Pulse:
These informations are for a single pulse on a cold resistor at 25 °C (not already used for a dissipation) and for pulses of
100 ms maximum duration.
The formula used to calculate E is:
with:
E (J): Pulse energy
P (W): Pulse power
t (s): Pulse duration
U (V): Pulse voltage
R (): Resistor
The energy calculated must be less than that allowed by the graph.
Repetitive or Superimposed Pulses:
The following formula is used to calculate the “equivalent“ energy of a repetitive pulse or the “equivalent energy“ of a pulse on
a resistor that is already dissipating power.
with:
E
c
(J): Equivalent pulse energy
E (J): Known pulse energy
P
r
: Resistor power rating
P
a
: Mean power being dissipated
The energy calculated must be less than that allowed by the graph and the average power dissipated (P
a
) must not exceed the
continuous power of resistor.
