T.C.R. Measuring Temperature + 25° C / + 75° C  
The resistance value of this resistor changes by its self-heating by power applied. Therefore, it is recommended to take its self-heating into consideration.  
Care must be taken that the resistors may be damaged by occurrence or application of the static electricity in equipment assembling processes.
