4. Static Electricity

• The LEDs are very sensitive to Static Electricity and surge voltage. So it is recommended

that a wrist band or an anti-electrostatic glove be used when handling the LEDs.

• All devices, equipment and machinery must be grounded properly. It is recommended that

precautions should be taken against surge voltage to the equipment that mounts the LEDs.

5. Heat Generation

• Thermal design of the end product is of paramount importance. Please consider the heat

generation of the LED when making the system design. The coefficient of temperature

increase per input electric power is affected by the thermal resistance of the circuit board

and density of LED placement on the board, as well as other components. It is necessary to

avoid intense heat generation and operate within the maximum ratings given in the

specification.

• The operating current should be desided after sonsidering the ambient maximum

temperature of LEDs.

6. Storage

• The LEDs should be stored at 30°C or less and 70%RH or less after being shippedand the

sorage life limits are 3 months. If the LEDs are stored for 3 months or more, they can be

stored for a year in a sealed container with nitrogen atmosphere and moisture absorbent

material.

• LED leads are gold okated Iron alloy. The gold surface may be affected by environments

which contain corrosive substances. Please avoid conditions which may cause the LED to

corrode, tarnish or discolor. This corrosion or discoloration may cause difficulty during

soldering operations. It is recommended that the LEDs be used as soon as possible.

• Please avoid rapid transistions in ambient temperature, especially in high humidity

environments where condensation can occur.
