• 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.
