Notice of Surge Load
Surge withstanding load voltage for the resistors cannot be guaranteed when the
undermentioned 4 items get to a remarkable overload in comparison with the
conditions shown by surge withstanding voltage in Anti-surge characteristics.
Please contact KOA in advance if such a case is anticipated.

For example: In the figure, a metal wire is placed
less than 5mm away from the resistor body, there is such a case that causes an
electric discharge by a surge load 10kV and then destroys the outer coating.
