1. RATED POWER:

Rated Power is the value of maximum load power specified at rated ambient temperature (usually 70℃).   
 
2. RATED VOLTAGE:

Rated Voltage is the value of maximum DC or AC voltage (rms) specified at rated ambient temperature.  RATED VOLTAGE =

3. MAXIMUM WORKING VOLTAGE:

Maximum Working Voltage is the maximum limiting value of above-mentioned Rated Voltage.
 
4. SHORT TIME OVERLOAD VOLTAGE:

Short Time Overload Voltage is the value of allowable overload voltage that can be applied in 5 seconds (Typically 2.5 times of above-mentioned Rated Voltage).
 
5. DIELECTRIC WITHSTANDING VOLTAGE:

Dielectric Withstanding Voltage is the value of allowable AC voltage (rms) that can be applied between the electrode and the outer coating in 1 minute.
 
6. DERATING CURVE:

 When the ambient temperature surpasses rated ambient temperature, the value of rated  power should be declines as per following DERATING CURVE (usually present as a percentage).
 
 



7. RESISTANCE TEMPERATURE COEFFICIENT (T.C.R.):

When the resistors used under different operating ambient temperature, the resistance value will change according to the different operating ambient temperature, usually present in PPM /℃.
