Terms & Definitions Dielectric Withstanding Voltage: Rated Power: A.C. voltage (rms) that can be applied to a designated spot between the electrode and the outer coating for one minute in the dielectric withstanding voltage test. The maximum value of power which can be continuously loaded to a resistor at a rated ambient temperature. Rated Voltage: Rated Ambient Temperature: The maximum value of D.C. voltage or A.C. voltage (rms) capable of being applied continuously to a resistor at the rated ambient temperature. Rated voltage shall be calculated from the following formula: The maximum ambient temperature at which a resistor is capable of being used continuously with the prescribed rated power. The rated ambient temperature refers to the temperature around the resistor inside the equipment, not to the air temperature outside the equipment. Rated Voltage(V) = Derating Curve: Rated Power(W) x Nominal Resistance Value (ohm) The curve that expresses the relation between ambient temperature and the maximum value of continuously loadable power at its temperature, which is generally expressed in percentage. However, it shall not exceed the maximum working voltage. Critical Resistance Value: The maximum nominal resistance value at which the rated power can be loaded without exceeding the maximum working voltage. The rated voltage is equal to the maximum working voltage in the critical resistance value. Temperature Coefficient of Resistance (T.C.R.): The rate of change in resistance value per 1°C in the prescribed temperature within the range of resistor operating temperature shall be expressed in the following formula: Maximum Working Value: R-R0 1 — — — x— —— — — x 106 T.C.R. (ppm/°C) = —— R0 T-T0 The maximum value of D.C. voltage or A.C. voltage (rms) capable of being applied continuously to a resistor or a resistor element. However, the maximum value of the applicable voltage is the rated voltage at the critical resistance value or lower. Where: R: Measured Resistance at T°C R0: Measured Resistance at T0°C T: Measured Test Temperature (°C) T0: Measured Base Temperature (°C) Maximum Overload Voltage: The maximum value of voltage capable of being applied to a resistor for five seconds in the short-time overload test. Typically the applied voltage in the short-time overload test shall be 2.5 times larger than the rated voltage. However, it shall not exceed the maximum overload voltage.
