Electrical Specifications

Temperature De-rating Curves

Storage / Environment Conditions

Products should be stored under the following environmental conditions.

Temperature:

+5 to +35 °C

Humidity:

45 to 85% relative humidity

Moisture Sensitivity Level

1, J-STD-020

Do not keep products in environments where they may be subject

to particulate contamination or harmful gases such as sulfuric acid or

hydrogen chloride as it may cause oxidization on electrodes, resulting poor

solderability.

Products should be stored in a space that does not expose to high

temperatures, vibration, or direct sunlight.

Products should be stored in the original airtight packaging

until use.
