IR Reflow Soldering Wave Soldering (Flow Soldering) (1) Time of IR reflow soldering at maximum temperature point 260°C ：10s (2) Time of wave soldering at maximum temperature point 260°C ：10s (3) Time of soldering iron at maximum temperature point 410°C ：5s
■Pul withstanding capacity
The single impul graph is the result of 50 impuls 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 impul voltage graph shown.

▓Continuous Pul
The continuous load graph was obtained by applying repetitive rectangular puls where the pul 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.

▓Frequency Behavior
Resistors are designed to function according to ohmic laws. This is basically true of resistors for frequencies up to 100kHz. At higher frequencies, there is an additional contribution to the impedance by an ideal resistor switched in ries 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.
