5.0 Derating Curve:
Resistors shall have a power rating based on continuous load operation at an ambient temperature
from -55℃ to 70℃. If the ambient temperature risen over 70℃, the power rating would be derate as
shown in figure 1.

6.0 Voltage rating:
Resistors shall have one voltage specifications:
1. Rated direct-current (DC) continuous working voltage
2. Approximate single-wave root-mean-square (RMS) alternating-current (AC) continuous working
voltage
We can calculate the Voltage from the following formula:
RCWV = √𝑃 × 𝑅

11.0 Precaution for storage/Transportation:
11.1 UNIOHM recommend the storage condition temperature: 15℃~35℃, humidity: 25%~75%.(Put
condition for individual product)
Even under UNIOHM recommended storage condition, solderability of products over 1 year old
will be degraded.
11.2 Store / transport cartons in the correct direction, which is indicated on a carton as a symbol.
Otherwise bent leads may occur due to excessive stress applied when dropping of a carton.
11.3 Product’s performance and soldered connections may deteriorate if the products are stored in
the following places:
11.3.1 Storage in high Electrostatic
11.3.2 Storage in direct sunshine、rain and snow or condensation
11.3.3 Where the products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3,
SO2, NO2.
