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

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

Frequency behaviour
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 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 behaviour of the
component on the printed-circuit board.

Handling Recommendations
When flow soldering - the land width must be smaller than the Chip Resistor
width to properly control the solder application. Generally, the land width
can be Chip Resistor width (W) x 0.7 to 0.8. When reflow soldering – solder
application amount can be adjusted. Thus the land width can be set to W x
1.0 to 1.3.
