Power Derating Characteristics
Rated Power shall be the load power corresponding to nominal wattage suitable
for continuous use at 70C ambient temperature. In case the ambient
temperature exceeds 70C, reduce the load power in accordance with Derating
curve in Fig. 1.

Product Assurance ASJ resistor shall warranty 24 months from the date of shipment.
ASJ resistors are RoHS compliance in accordance to RoHS Directive 2011/65/EU.
Rated Voltage: Rated voltage: DC current or AC voltage (rms) base on the rated power.
The voltage can be calculated by the following formula. If the calculated value exceeds
the Max. voltaget specified in the table 3.1.1, the Max. voltage rating is set as the
voltage rating.
E = √P. R
Where E : Rated Voltage (V)
P : Rated Power (W)
R : Nominal Resistance ()
3.10.1 Current Rating
Rated current: DC current or AC current (rms) base on the rated power.
The current can be calculated by the following formula. If the calculated value
exceeds the Max. current specified in the table 3.1.2, the Max. current rating is
set as the current rating.

I=Rated current(A)
P=Power rating
