Resistor Paramaters

Impulse strength is the maximum allowed short-duration (impulse) electric energy that the resistor can withstand without exceeding the limiting temperature.
Limiting voltage, also referred to as dielectric strength, is the maximum allowable voltage that can be applied to the resistor.
Limiting current is the maximum allowable current through the resistor.
Insulation strength, also known as breakdown rating, is the maximum allowable voltage between the resistance element and the environment (chassis or heat sink).
Standard conditions are the measurement conditions for defining the resistor value, tolerance and stability. In Riedon laboratory and production processes, the reference temperature is 25degC +/- 2degC.
