*: Ultra High Power: double side printed resistor element
Operating Voltage=√(P*R) or Max. Operating Voltage listed above, whichever is lower.
Overload Voltage=2.5*√(P*R) or Max. Overload Voltage listed above, whichever is lower.
The power rating depends on the maximum temperature of the resistive element. Due to the power dissipation of the resistor, the
temperature of the resistive element will rise depending on the condition of heat dissipation from PCB. The maximum power rating in
application only applies if the temperature of the resistive element is not exceed 155 ° C.

■Lightning Surge
Resistors are tested in accordance with IEC 60115-1 using both 1.2/50us and 10/700 pulse shapes. The limit of acceptance is a
shift in resistance of less than 1% from the initial value.

■Pulse withstanding capacity
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 70C.
Again the limit of acceptance was a shift in
resistance of less than 1% from the initial value.
