Resistor sizes might vary depending on pulse voltage, load current,
pulse rate and ambient temperature, etc.
** We can support lower Temperature
Coefficient 50ppm, 150ppm, and 200ppm requirement.
###
For a given rated power Resistor, the actual
max. pulse voltage depends on the rated resistance
value, pulse width, duty cycle, duration between two
adjacent pulses, number of pulses per second / minute
and ambient temperature.
