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.
MLFA Series Single Pulse (100 Ohm)
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 70ºC. Again the limit of acceptance
was a shift in resistance of less than 1% from the initial value.

MLFA Series Pulse Voltage (100 Ohm)
Frequency behavior
Resistors are designed to function according to Ohmic laws. This is basically true of resistors for frequencies up to 100
kHz. At higher frequencies, there is an additional contribution to the impedance by an ideal resistor switched in series
with a coil and both switched parallel to a capacitor. The values of the capacitance and inductance are mainly
determined by the dimensions of the terminations and the conductive path length.
The environment surrounding components has a large influence on the behavior of the component on the printed-circuit
board.
