■Features
・Excellent anti-sulfuration characteristic due to using high
sulfuration-proof inner top electrode material.
・High heat resistance that can be used even at high temperatures
of 155℃ or higher. The maximum operating temperature of Sn
plating products compatible with solder mounting is 175℃.
・Excellent heat resistance and weather resistance are ensured by
the use of metal glaze thick film.

※1 If you use at the rated power, please keep the condition that the terminal of the resistor is below the rated terminal part temperature. Please refer to the derating curves based on the terminal
temperature of right side on the next page.
If any questions arise whether to use the“Rated Ambient Temperature”or the“Rated Terminal Part Temperature”in your usage conditions, please give priority to the“Rated Terminal Part
Temperatu r e ”.
For more details, please refer to“Introduction of the derating curves based on the terminal part temperature”on the beginning of our catalog.
