Metal Film Melf Resistor Resistive Product Solutions 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. MLF Series Single Pulse (100 Ohm) MLF0207 MLF0204 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 70C. Again the limit of acceptance was a shift in resistance of less than 1% from the initial value.

Metal Film Melf Resistor Resistive Product Solutions 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.
