Designed resistance value usually indicated on the resistor.
Maximum allowable power at rated temperature. Some of our chip resistor arrays and networks specify the whole power rating as a package.
Maximum ambient temperature at which the power rating may be applied continuously. The rated ambient temperature refers to the temperature around the resistor mounted inside the equipment, not to the air temperature outside the equipment.
Rated Terminal Part Temperature
Maximum terminal part temperature of the surface mount resistor at which the power rating may be applied continuously. Includes the temperature rise by self heat generation.
Curve that expresses the relation between ambient temperature and the maximum allowable power, which is generally expressed in percentage.
Maximum allawable D.C. or A.C. voltage(rms), capable to be continuously applied to a resistor or a resistor element under the rated ambient temperature or terminal part temperature, which is calculated from the rated power and nominal resistance using the following formula.
Rated voltage shall not exceed the max. working voltage.
