Resistors shall have a power rating based on continuous load operation at an ambient
temperature from -55℃ to 70℃. For temperature in excess of 70℃, the load shall be derate as shown in
figure 1
4.0 Voltage rating:
Resistors should have a direct-current (DC) continuous voltage rating and an alternating-current (AC)
continuous voltage rating relates to Power Rating, formula shown as below:
RCWV = √𝑃𝑃 ∗ 𝑅𝑅
RCWV: Rated dc or RMS ac continuous working voltage at commercial-line frequency and waveform (Volt.)
P:
Power Rating (Watt.)
R:
Nominal Resistance (Ohm)
Resistors will be burned out if it overload, such as higher than the maximum value of series’ RCWV.
And we named 2.5 times RCWV is OVERLOAD Voltage.

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.
(Put condition for each product) may 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 performance and soldered connections may deteriorate if the products are stored in the
following places:
11.3.01 In high electrostatic;
11.3.02 In direct sunshine, rain, snow or condensation;
11.3.03 Exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2.
