Metal Film Precision MELF Resistor
Pulse withstanding capacity
The single impulse graph is the result of 50 impulses of rectangular shape applied at one-minute
intervals. The limit of acceptance was a shift in resistance of less than 1% from the initial value.
The power applied was subject to the restrictions of the maximum permissible impulse voltage
graph shown

Metal Film Precision MELF Resistor
Continuous Pulse
The continuous load graph was obtained by applying repetitive rectangular pulses where the
pulse period was adjusted so that the average power dissipated in the resistor was equal to its
rated power at 70°C. Again the limit of acceptance was a shift in resistance of less than 1% from
the initial value
