*1 Measurement Temperature: +25°C/+125°C. Cold T.C.R. (-55°C/+25°C) is -50~+25x10-6/K
*2 Please inquire about E-192
If any questions arise whether to use the “Rated Ambient Temperature” or the “Rated Terminal Part Temperature,” please give priority to the “Rated Terminal Part Temperature.”
Prior to use and for more details refer to “Introduction of the derating curves in the terminal part temperature” in the beginning of the catalog.

Regarding the temperature rise,
the value of the temperature varies
per conditions and board for use
since the temperature is measured
under our measuring conditions.

Pulse Duration
(ms)
The maximum applicable voltage is equal to the max. overload
voltage. Please ask us about the resistance characteristic of
continuous applied pulse. The pulse endurance values are not
assured values, so be sure to check the products on actual
equipment when you use them.
